drm/amd/display: Disable PSR-SU on Parade 08-01 TCON too

Stuart Hayhurst has found that both at bootup and fullscreen VA-API video
is leading to black screens for around 1 second and kernel WARNING [1] traces
when calling dmub_psr_enable() with Parade 08-01 TCON.

These symptoms all go away with PSR-SU disabled for this TCON, so disable
it for now while DMUB traces [2] from the failure can be analyzed and the failure
state properly root caused.
