Add gk20a_channel_from_id() to retrieve a channel, given a raw channel
ID, with a reference taken (or NULL if the channel was dead). This makes
it harder to mistakenly use a channel that's dead and thus uncovers bugs
sooner. Convert code to use the new lookup when applicable; work remains
to convert complex uses where a ref should have been taken but hasn't.
The channel ID is also validated against FIFO_INVAL_CHANNEL_ID; NULL is
returned for such IDs. This is often useful and does not hurt when
unnecessary.
However, this does not prevent the case where a channel would be closed
and reopened again when someone would hold a stale channel number. In
all such conditions the caller should hold a reference already.
The only conditions where a channel can be safely looked up by an id and
used without taking a ref are when initializing or deinitializing the
list of channels.

- In vGPU code path, function vgpu_channel_abort_cleanup() does not
obtain channel reference before using the channel structure
(channel_gk20a)
- vgpu_channel_abort_cleanup() is called by vgpu_intr_thread() which
runs commands obtained from interrupt queue from RM server.
- If there is a scenario where gk20a_channel_release() function runs
before guest receives notification from RM server to abort channel
cleanup, channel gets freed before vgpu_channel_abort_cleanup() runs.
- However, because vgpu_channel_abort_cleanup() does not take explicit
reference to the channel, it ends up accessing structures
(such as ch->g) which are set to NULL and thus we end up in a crash.
- This patch explicitly takes reference of channel before
vgpu_channel_abort_cleanup() is called.
- If gk20a_channel_release() runs before vgpu_channel_abort_cleanup()
and ends up freeing channel, we dont get reference to freed
channel in vgpu_channel_abort_cleanup() and thus we return from
function rather than continuing with freed channel as was the case
previously.

1. Implement the following vgpu functions to support clk-arb:
- vgpu_clk_get_range() to return min and max freqs from
supported frequencies
- implement vgpu_clk_get_round_rate() which sets rounded
rate to input rate. Rounding is handled in RM Server
- modify vgpu_clk_get_freqs() to retrieve freq table in IVM
memory instead of copying the value in array as part of cmd
message.
2. Add support for clk-arb related HALs for vgpu.
3. support_clk_freq_controller is assigned true for vgpu
provided guest VM has the privilege to set clock frequency.

-Created struct nvgpu_acr to hold acr module related member
within single struct which are currently spread across multiple structs
like nvgpu_pmu, pmu_ops & gk20a.
-Created struct hs_flcn_bl struct to hold ACR HS bootloader specific members
-Created struct hs_acr to hold ACR ucode specific members like bootloader data
using struct hs_flcn_bl, acr type & falcon info on which ACR ucode need to run.
-Created acr ops under struct nvgpu_acr to perform ACR specific operation,
currently ACR ops were part PMU which caused to have always dependence
on PMU even though ACR was not executing on PMU.
-Added acr_remove_support ops which will be called as part of
gk20a_remove_support() method, earlier acr cleanup was part of
pmu remove_support method.
-Created define for ACR types,
-Ops acr_sw_init() function helps to set ACR properties
statically for chip currently in execution & assign ops to point to
needed functions as per chip.
-Ops acr_sw_init execute at early as nvgpu_init_mm_support calls acr
function to alloc blob space.
-Created ops to fill bootloader descriptor & to patch WPR info to ACR uocde
based on interfaces used to bootstrap ACR ucode.
-Created function gm20b_bootstrap_hs_acr() function which is now common
HAL for all chips to bootstrap ACR, earlier had 3 different function for
gm20b/gp10b, gv11b & for all dgpu based on interface needed.
-Removed duplicate code for falcon engine wherever common falcon code can be used.
-Removed ACR code dependent on PMU & made changes to use from nvgpu_acr.

Because the new functions do not work without a pointer to struct
gk20a, and piping it just for logging is excessive, some log messages

NVGPU_SUBMIT_GPFIFO_FLAGS_RESCHEDULE_RUNLIST causes host to expire
current timeslice and reschedule from front of runlist.
This can be used with NVGPU_RUNLIST_INTERLEAVE_LEVEL_HIGH to make a
channel start sooner after submit rather than waiting for natural
timeslice expiration or block/finish of currently running channel.

Currently callbacks from the PM_QOS framework (for
thermal events), result in a RPC call to set GPU frequency.
Since the governor will now be responsible for setting desired
rate, the max PM_QOS callback will now cap the possible
GPU frequency w/ a new RPC call to the server. The server
is responsible for setting the ultimate frequency
based on the cap & desired rates.

In order to perform timestamps correlation for FECS
traces, we need to collect GPU / GPU timestamps
samples. In virtualization case, it is possible for
a guest to get GPU timestamps by using read_ptimer.
However, if the CPU timestamp is read on guest side,
and the GPU timestamp is read on vm-server side,
then it introduces some latency that will create an
artificial offset for GPU timestamps (~2 us in
average). For better CPU / GPU timestamps correlation,
Added a command to collect all timestamps on vm-server
side.
