drm: add PSR2 support and capability definition as per eDP 1.5
[why & how]
As per eDP 1.5 spec, add the below two DPCD bit fields for PSR-SU
support and capability:
1. DP_PSR2_WITH_Y_COORD_ET_SUPPORTED
2. DP_PSR2_SU_AUX_FRAME_SYNC_NOT_NEEDED
changes in v2
------------------
* fixed the typo
* explicitly list what DPCD bit fields are added
