gk20a_err() and gk20a_warn() require a struct device pointer,
which is not portable across operating systems. The new nvgpu_err()
and nvgpu_warn() macros take struct gk20a pointer. Convert code
to use the more portable macros.

Rename the nvgpu DMA APIs from gk20a_gmmu_alloc* to nvgpu_dma_alloc*.
This better reflects the purpose of the APIs (to allocate DMA suitable
memory) and avoids confusion with GMMU related code.

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.

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.

Instead of using Linux APIs for mutex and spinlocks
directly, use new APIs defined in <nvgpu/lock.h>
Replace Linux specific mutex/spinlock declaration,
init, lock, unlock APIs with new APIs
e.g
struct mutex is replaced by struct nvgpu_mutex and
mutex_lock() is replaced by nvgpu_mutex_acquire()
And also include <nvgpu/lock.h> instead of including
<linux/mutex.h> and <linux/spinlock.h>
Add explicit nvgpu/lock.h includes to below
files to fix complilation failures.

Reorganize the HW headers of gk20a. The headers are moved to a
new directory:
include/nvgpu/hw/gk20a
And from the code are included like so:
#include <nvgpu/hw/gk20a/hw_pwr_gk20a.h>
This is the first step in reorganizing all of the HW headers for
gm20b, gm206, etc. This is part of a larger effort to re-structure
and make the driver more readable and scalable.

We use &ch->error_notifier_mutex to protect
writes and free of error notifier
But we currently do not protect reading of
notifier in gk20a_fifo_set_ctx_mmu_error()
and vgpu_fifo_set_ctx_mmu_error()
Add new API gk20a_set_error_notifier_locked()
which is same as gk20a_set_error_notifier()
but without the locks.
In *_fifo_set_ctx_mmu_error() APIs, acquire
the mutex explicitly, and then use this new
API
gk20a_set_error_notifier() will now just call
gk20a_set_error_notifier_locked() within
a mutex

Because all of the buffers haven't been tested to work in vidmem yet,
rename calls to gk20a_gmmu_alloc{,attr,_map,_map_attr} to have _sys at
the end to declare explicitly that vidmem is used. Enabling vidmem for
each now is a matter of removing "_sys" from the function call.

To support vidmem, pass g and mem_desc to the buffer memory accessor
functions. This allows the functions to select the memory access method
based on the buffer aperture instead of using the cpu pointer directly
(like until now). The selection and aperture support will be in another
patch; this patch only refactors these accessors, but keeps the
underlying functionality as-is.
gk20a_mem_{rd,wr}32() work as previously; add also gk20a_mem_{rd,wr}()
for byte-indexed accesses, gk20a_mem_{rd,wr}_n() for memcpy()-like
functionality, and gk20a_memset() for filling buffers with a constant.
The 8 and 16 bit accessor functions are removed.
vmap()/vunmap() pairs are abstracted to gk20a_mem_{begin,end}() to
support other types of mappings or conditions where mapping the buffer
is unnecessary or different.
Several function arguments that would access these buffers are also
changed to take a mem_desc instead of a plain cpu pointer. Some relevant
occasions are changed to use the accessor functions instead of cpu
pointers without them (e.g., memcpying to and from), but the majority of
direct accesses will be adjusted later, when the buffers are moved to
support vidmem.

We currently free sync when we find job list empty
If aggressive_sync is set to true, we try to free
sync during channel unbind() call
But we rarely free sync from channel_unbind() call
since freeing it when job list is empty is
aggressive enough
Hence remove sync free code from channel_unbind()
Implement refcounting for sync:
- get a refcount while submitting a job (and
allocate sync if it is not allocated already)
- put a refcount while freeing the job
- if refcount==0 and if aggressive_sync_destroy is
set, free the sync
- if aggressive_sync_destroy is not set, we will
free the sync during channel close time

Previously, only "high" priority bare channels were interleaved
between all other bare channels and TSGs. This patch decouples
priority from interleaving and introduces 3 levels for interleaving
a bare channel or TSG: high, medium, and low. The levels define
the number of times a channel or TSG will appear on a runlist (see
nvgpu.h for details).
By default, all bare channels and TSGs are set to interleave level
low. Userspace can then request the interleave level to be increased
via the CHANNEL_SET_RUNLIST_INTERLEAVE ioctl (TSG-specific ioctl will
be added later).
As timeslice settings will soon be coming from userspace, the default
timeslice for "high" priority channels has been restored.

Current sequence in gk20a_disable_channel() is
- disable channel in gk20a_channel_abort()
- adjust pending fence in gk20a_channel_abort()
- preempt channel
But this leads to scenarios where syncpoint has
min > max value
Hence to fix this, make sequence in gk20a_disable_channel()
- disable channel in gk20a_channel_abort()
- preempt channel in gk20a_channel_abort()
- adjust pending fence in gk20a_channel_abort()
If gk20a_channel_abort() is called from other API where
preemption is not needed, then use channel_preempt
flag and do not preempt channel in those cases
