Remove dependency for nvgpu to invoke devfreq govenor on every
gk20a_busy/idle() call. This dependency was originally necessary to
track GPU load (busy vs idle) in software. However, since we currently
read the load GPU from HW/PMU there is no need to invoke the devfreq
governor in this path. Instead it can use timer-based polling.

It's technically possible for a thread to exit without first calling
nvgpu_thread_stop() in another, so mark the thread exit status from the
thread after it has finished instead of in nvgpu_thread_stop(). Do this
by starting the thread as a proxy function which calls the actual thread
function and then sets the flag.
Also, add a new flag to actually signify the running state because the
thread->task going null abruptly would break nvgpu_thread_stop().
This does not guarantee that the kernel thread itself has stopped, but
the function which can be considered as an "nvgpu thread" will be.

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

To support deterministic channels even with platforms where railgating
is supported, have each deterministic-marked channel hold a power
reference during their lifetime, and skip taking power refs for jobs in
submit path for those.
Previously, railgating blocked deterministic submits in general because
of gk20a_busy()/gk20a_idle() calls in submit path possibly taking time
and more significantly because the gpu may need turning on which takes a
nondeterministic and long amount of time.
As an exception, gk20a_do_idle() can still block deterministic submits
until gk20a_do_unidle() is called. Add a rwsem to guard this. VPR resize
needs do_idle, which conflicts with deterministic channels' requirement
to keep the GPU on. This is documented in the ioctl header now.
Make NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_NO_JOBTRACKING always
set in the gpu characteristics now that it's supported. The only thing
left now blocking NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_FULL is
the sync framework.
