drm/amd/display: Update Interface to Check UCLK DPM
[Why]
Videos using YUV420 format may result in high power being used.
Disabling MPO may result in lower power usage.
Update interface that can be used to check power profile of a dc_state.
[How]
Allow pstate switching in VBlank as last entry in strategy candidates.
Add helper functions that can be used to determine power level:
-get power profile after a dc_state has undergone full validation
