Add abstractions for the following:
msleep()
udelay()
usleep_range()
These functions are only a subset of the available Linux delay and sleep
functions but this seems to be what we use and what is actually useful
for driver development.

This implementation is needed to remove nvgpu's
dependency on Linux specific list implementation
Define a list node as
struct nvgpu_list_node *node;
Define below common APIs:
nvgpu_init_list_node() - initialize list node
nvgpu_list_add() - add new node to list
nvgpu_list_add_tail() - add new node to end of list
nvgpu_list_del() - delete node from list
nvgpu_list_empty() - check if list is empty
Define below macros to simplify access to list:
nvgpu_list_entry() - convert list node to parent
nvgpu_list_next_entry() - find next entry in list
nvgpu_list_first_entry() - first entry in list
nvgpu_list_for_each_entry() - iterator for list
nvgpu_list_for_each_entry_safe() - deletion safe iterator

ctrl_gk20a.c had some direct accesses to hardware. These violate the
HAL rules, because we don't have per-GPU ctrl, and thus the code
cannot be made GPU independent.

accessing timer. Remove #includes of all hardware headers.

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.

The nvgpu timer API prints a message when the timer expires, but
expiration of that does not necessarily mean here that the job has
actually timed out, which is tested by comparing gp_get. Change the
expiration check to just peek instead of the default which prints to

Commit 8f3875393e7a6bd0fc03afdb1fa99b7e33b71576 ("abstract away dma
alloc attrs") added an implicit NVGPU_DMA_NO_KERNEL_MAPPING for the
function that allocates vidmem buffers, but the functions
gk20a_gmmu_alloc_map_vid and gk20a_gmmu_alloc_map got overlooked and use
no flags which now triggers a warning. Make those cases alloc the
vidmem buffer with the no kernel mapping flag as it should have been,
because kernel mappings of vidmem are not supported.

There were still a few remaining loops where we did not use
nvgpu_timeout and required Tegra specific functions for detecting if
timeout should be skipped. Replace all of them with nvgpu_timeout and
remove including chip-id.h where possible.
FE power mode timeout loop also used wrong delay value. It always
waited for the whole max timeout instead of looping with smaller
increments.
If SEC2 ACR boot fails to halt, we should not try to check ACR result
from mailbox. Add an early return for that case.

Clean up gk20a.c by removing direct accesses to MC and moving the
accesses to happen via MC HAL.
The chip detection logic has to violate the HAL and call gk20a
version directly, because HAL ops cannot be set up before chip has
been identified.

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
