This function is an internal function to the VM manager that allocates
virtual memory space in the GVA allocator. It is unfortunately used in
the vGPU code, though. In any event, this patch cleans up and moves the
implementation of these functions into the VM common code.

Add the following ioctls
- NVGPU_CHANNEL_IOCTL_GET_TIMESLICE for channel timeslice in us
- NVGPU_TSG_IOCTL_GET_TIMESLICE for TSG timeslice in us
If timeslice has not been set explicitly, ioctl returns the
default timeslice that will be used when programming the runlist
entry.

The vm_reserve_va_node struct is essentially a special VM area that
can be used for sparse mappings and fixed mappings. The name of this
struct is somewhat confusing (as node is typically used for list
items). Though this struct is a part of a list it doesn't really
make sense to call this a list item since it's much more. Based on
that the struct has been renamed to nvgpu_vm_area to capture the
actual use of the struct more accurately.
This also moves all of the management code of vm areas to a new file
devoted solely to vm_area management.
Also add a brief overview of the VM architecture. This should help
other people follow along the hierachy of ownership and lifetimes in
the rather complex MM code.

This patch begins splitting out the VM implementation from mm_gk20a.c and
moves it to common/linux/vm.c and common/mm/vm.c. This split is necessary
because the VM code has two portions: first, an interface for the OS
specific code to use (i.e userspace mappings), and second, a set of APIs
for the driver to use (init, cleanup, etc) which are not OS specific.
This is only the beginning of the split - there's still a lot of things
that need to be carefully moved around.

This patch begins the major rework of the GPU's virtual memory manager
(VMM). The VMM is the piece of code that handles the userspace interface
to buffers and their mappings into the GMMU. The core data structure is
the VM - for now still known as 'struct vm_gk20a'. Each one of these
structs represents one addres space to which channels or TSGs may bind
themselves to.
The VMM splits the interface up into two broad categories. First there's
the common, OS independent interfaces; and second there's the OS specific
interfaces.
OS independent
--------------
This is the code that manages the lifetime of VMs, the buffers inside
VMs (search, batch mapping) creation, destruction, etc.
OS Specific
-----------
This handles mapping of buffers represented as they are represented by
the OS (dma_buf's for example on Linux).
This patch is by no means complete. There's still Linux specific functions
scattered in ostensibly OS independent code. This is the first step. A
patch that rewrites everything in one go would simply be too big to
effectively review.
Instead the goal of this change is to simply separate out the basic
OS specific and OS agnostic interfaces into their own header files. The
next series of patches will start to pull the relevant implementations
into OS specific C files and common C files.

Hide the Linux specific nvgpu_mem fields so that in subsequent patches
core code can instead of using struct sg_table it can use mem_desc.
Routines for accessing system specific fields will be added as needed.
This is the first step in a fairly major overhaul of the GMMU mapping
routines. There are numerous issues with the current design (or lack
there of): massively coupled code, system dependencies, disorganization,
etc.

pending_sema_waits and a few other variables in struct gk20a is used
in gk20a shutdown path but we didn't initialize them in vgpu. I added
a function vgpu_init_vars dedicated to init variables for struct gk20a.
The native code also similar function nvgpu_init_vars().
This is a quick fix. Finally, the common probe code is better be put
in common function btween vgpu and native gpu.

Move code that touches host registers and instance block to fifo HAL.
This involves adding HAL ops for the fifo HAL functions that get
called from outside fifo. This clears responsibility of channel by
leaving it only managing channels in software and push buffers.
channel had member ramfc defined, but it was not used, to remove it.
pbdma_acquire_val consisted both of channel logic and hardware
programming. The channel logic was moved to the caller and only
hardware programming was moved.

This change refactors the teardown in remove to ensure that it is
possible to unload the driver while leaving fds open. This is achieved
by making sure that the SW state is kept alive till all fds are closed
and by checking that subsequent calls to ioctls after the teardown fail.
Normally, this would be achieved ny calls into gk20a_busy(), but in
kickoff we dont call into that to reduce latency, so we need to check
the driver status directly, and also in some of the functions
as we need to make sure the ioctl does not dereference the device or
platform struct

Support for hwpm reservations in the virtual case:
- Add session ops for checking and setting global and context reservations, and
releasing reservations
- in the native case, these just update reservation counts and flags
- in the vgpu case, when the reservation count is 0, check with the RM server
that a reservation is possible: for global reservations, no other guest
can have a reservation; for context reservations, no other guest can have
a global reservation
- in the vgpu case, when the reservation count is decremented to 0, notify
the RM server that the guest no longer has any reservations

Move all programming of FB to fb_*.c files, and remove the inclusion
of FB hardware headers from other files.
TLB invalidate function took previously a pointer to VM, but the new
API takes only a PDB mem_desc, because FB does not need to know about
higher level VM.
GPC MMU is programmed from the same function as FB MMU, so added
dependency to GR hardware header to FB.
GP106 ACR was also triggering a VPR fetch, but that's not applicable
to dGPU, so removed that call.

Implement a worker thread to replace the delayed works in channel
watchdog and job cleanups. Watchdog runs by polling the channel states
periodically, and job cleanup is performed on channels that are appended
on a work queue consumed by the worker thread. Handling both of these
two in the same thread makes it impossible for them to cause a deadlock,
as has previously happened.
The watchdog takes references to channels during checking and possibly
recovering channels. Jobs in the cleanup queue have an additional
reference taken which is released after the channel is processed. The
worker is woken up from periodic sleep when channels are added to the
queue.
Currently, the queue is only used for job cleanups, but it is extendable
for other per-channel works too. The worker can also process other
periodic actions dependent on channels.
Neither the semantics of timeout handling or of job cleanups are yet
significantly changed - this patch only serializes them into one
background thread.
Each job that needs cleanup is tracked and holds a reference to its
channel and a power reference, and timeouts can only be processed on
channels that are tracked, so the thread will always be idle if the
system is going to be suspended, so there is currently no need to
explicitly suspend or stop it.
