drm/amd: Add detailed GFXOFF stats to debugfs
Add debugfs interface to log GFXOFF statistics:
- Read amdgpu_gfxoff_count to get the total GFXOFF entry count at the
time of query since system power-up
- Write 1 to amdgpu_gfxoff_residency to start logging, and 0 to stop.
Read it to get average GFXOFF residency % multiplied by 100
during the last logging interval.
Both features are designed to be keep the values persistent between
suspends.
