drm/amd/display: Set minimum requirement for using PSR-SU on Rembrandt

Browse Source 
A number of parade TCONs are causing system hangs when utilized with
older DMUB firmware and PSR-SU. Some changes have been introduced into
DMUB firmware to add resilience against these failures.

Don't allow running PSR-SU unless on the newer firmware.
