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

- 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

We have a gk20a_busy() call in gk20a_buffer_convert_gpu_to_cde()
and we again call gk20a_busy() in gk20a_submit_channel_gpfifo()
If gk20a_do_idle() is triggered in between these two calls,
then this leads to a deadlock and results in idle failure
Hence to avoid this take power refcount in a more fine-grained
way i.e. in gk20a_cde_convert() instead of taking in
gk20a_buffer_convert_gpu_to_cde()
Keep gk20a_cde_execute_buffer() out of the gk20a_busy()/
gk20a_idle() pair since we take power refcount in submit path
anyways
Add correct error handling path in gk20a_cde_convert()

In gk20a_cde_convert(), we hold cde_app.mutex almost
for everything which is unnecessary
Also, this causes a deadlock scenario when gk20a_do_idle()
is called
In some cases it is possible that Thread 1
holds the lock and is trying to power on GPU, and
Thread 2 is trying to power off GPU and then grab
cde_app.mutex to cleanup GPU state
To fix this, grab the mutex only for gk20a_cde_get_context()
and then release it

VBIOS might change size of the power policy table and add new fields.
So driver should validate a minimum size, not absolute size.
Also driver should use header size from data read from vbios
to parse the table further.

Don't use enum dma_attr in the gk20a_gmmu_alloc_attr* functions, but
define nvgpu-internal flags for no kernel mapping, force contiguous, and
read only modes. Store the flags in the allocated struct mem_desc and
only use gk20a_gmmu_free, remove gk20a_gmmu_free_attr. This helps in OS
abstraction. Rename the notion of attr to flags.
Add implicit NVGPU_DMA_NO_KERNEL_MAPPING to all vidmem buffers
allocated via gk20a_gmmu_alloc_vid for consistency.
Fix a bug in gk20a_gmmu_alloc_map_attr that dropped the attr
parameter accidentally.

When we get a PBDMA MMU fault, we won't be able to map the MMU id
into an engine id for reset. We still pass FIFO_INVAL_ENGINE_ID to
gk20a_fifo_should_defer_engine_reset() which causes an unnecessary
debug spew.
Check for FIFO_INVAL_ENGINE before calling
gk20a_fifo_should_defer_engine_reset().

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.
