drm/amd/powerplay: add UMD P-state in powerplay.
This feature is for UMD to run benchmark in a
power state that is as steady as possible. kmd
need to fix the power state as stable as possible.
now, kmd support four level:
profile_standard,peak,min_sclk,min_mclk
move common related code to amd_powerplay.c
