drm/amdgpu: add custom power policy support in sysfs
when cat pp_power_profile_mode on Vega10
NUM MODE_NAME BUSY_SET_POINT FPS USE_RLC_BUSY MIN_ACTIVE_LEVEL
0 3D_FULL_SCREEN : 70 60 1 3
1 POWER_SAVING : 90 60 0 0
2 VIDEO*: 70 60 0 0
3 VR : 70 90 0 0
4 COMPUTER : 30 60 0 6
5 CUSTOM : 0 0 0 0
the result show all the profile mode we can support and custom mode.
user can echo the num(0-4) to pp_power_profile_mode to select the profile
mode or can echo "5 value value value value" to enter CUSTOM mode.
the four parameter is set_point/FPS/USER_RLC_BUSY/MIN_ACTIVE_LEVEL.
