fa8ca3fb19 gpu: nvgpu: re-enable elpg after golden img init 
Typically, the PMU init thread will finish up long
before the golden context image has been initialized,
which means that ELPG hasn't truly been enabled at that
point.

Create a new function, nvgpu_pmu_reenable_pg(), which
checks if elpg had been enabled (non-zero refcnt), and
if so, disables then re-enables it.

Call this function from nvgpu_gr_obj_ctx_alloc() after
the golden context image has been initialized to ensure
that elpg is truly enabled.

6dbf8e3d58 gpu: nvgpu: Remove unused code from common.top 
Remove following error paths as they would never get called:
1. In gm20b_device_info_parse_enum:
   - This is a private HAL and is only called by get_device_info HAL.
   - It gets called only for table entry with entry type = enum.
   - So we remove the check if(entry_type != enum)...

2. In gp10b_device_info_parse_data:
   - This is a private HAL and is only called by get_device_info HAL.
   - It gets called only for table entry with entry type = data.
   - So we remove the check if(entry_type != data)...

3. In gp10b_get_device_info
   - entry corresponds to 2 bit extracted from the table_entry.
   - So, entry can have only 4 possible values.
   - We would never reach the else case; hence remove it.

c58029ad24 gpu: nvgpu: fix race for nvgpu_thread_stop 
The pmu init thread typically returns immediately
without calling nvgpu_thread_should_stop().

pmu_pg_kill_task() checks if the thread is running, and
if it is, calls nvgpu_thread_stop().

However, there's a race condition where the init thread could
have exited between the time that kill_task() checked the
running flag and the time we actually stop the thread, leading
to a kernel crash.

Fix this by making the running flag in the nvgpu_thread struct
atomic. Both the thread proxy function and the thread_stop()
function will set the flag to false.

In the case of nvgpu_thread_proxy(), if the flag is already false,
then nvgpu_thread_stop() has already reset it, at which point we
just wait for nvgpu_thread_should_stop() to return true.

In the case of nvgpu_thread_stop(), if the flag is already false,
then the thread proxy function has already exited, and there is
nothing more to do.

44a28012de gpu: nvgpu: fix MISRA 5.9 violation 
MISRA Advisory Rule 5.9 states that identifiers that define
objects or functions with internal linkage should be unique.

While it is permissible for an inline function with internal
linkage to be defined in a single header file the same is not
true for data objects.

This change moves the aperture_name[] string table to within
the nvgpu_aperture_str() function to comply with this advisory
rule.

Because the size of the table is relatively small (< 40 bytes
for the strings) the storage class is changed to automatic.

d23ad1d829 gpu: nvgpu: Remove unused therm event 
Currently for every +/-5 degC change in
temperature, PMU internally evaluate VF curve on
temp change and will send VFE callback to NVGPU for
initiating change seq to program voltage and frequency.
This is the only callback we receive on temp change
which we handle in perf unit, and we don't have any
other temp events raised by PMU.
So, deleting the therm event handler.
