drm/amd/display: Add PPS immediate update flag for DCN2

Browse Source 
[Why]
This change is needed for DCN2 to make use of the immediate_update
flag. With this flag, update to PPS will be immediate, rather than
always taking place on dig_update signal.

[How]
Set AFMT_GENERIC7_FRAME/IMMEDIATE_UPDATE bits depending on flag
value.
