3c7cf8b75a gpu: nvgpu: fix MISRA 10.5 issue in timeout code 
This change switches nvgpu_timeout_peek_expired() to return a bool
instead of an int to remove advisory rule MISRA 10.5 violations.

MISRA 10.5 states that the value of an expression should not be
cast to an inappropriate essential type.

318d6451e9 gpu: nvgpu: Improve accuracy of dGPU clk measurement 
- This patch replaces "nvgpu_current_time_ms" with "nvgpu_hr_timestamp_us".
- "nvgpu_hr_timestamp_us" gives timestamp in microseconds and has better
accuracy than "nvgpu_current_time_ms" (which gives timestamp in millisecond)
