drm/amd: Disable PSR-SU on Parade 0803 TCON
A number of users have reported that there are random hangs occurring
caused by PSR-SU specifically on panels that contain the parade 0803
TCON. Users have been able to work around the issue by disabling PSR
entirely.
To avoid these hangs, disable PSR-SU when this TCON is found.
