Mahantesh Kumbar 96cf9748a7 gpu: nvgpu: nvgpu_thread to handle PMU state changes ...

- Replaced schedule_worker() with nvgpu_thread along
with nvgpu_cond_wait() to handle PMU state machine
changes during boot.

- Added new state "PMU_STATE_EXIT" to exit
PMU state machine loop & wait for the
thread stop signal.

- In gk20a_init_pmu_setup_sw() thread creates &
starts thread execution to handle PMU state changes.

- In pmu_destroy() thread post PMU_STATE_EXIT
& waits for pending operation to complete
before thread destroy.
