drm/amd/display: expose AMD specific DPCD for PSR-SU-RC support
[why & how]
Expose vendor specific DPCD registers for rate controlling the eDP sink
TCON's refresh rate during PSR active. When used in combination with
PSR-SU and Freesync, it is called PSR-SU Rate Contorol, or PSR-SU-RC for
short.
v2: Add all DPCD registers required
