Mario Limonciello e7ab758741 drm/amd/display: Disable PSR-SU on Parade 0803 TCON again
When screen brightness is rapidly changed and PSR-SU is enabled the
display hangs on panels with this TCON even on the latest DCN 3.1.4
microcode (0x8002a81 at this time).

This was disabled previously as commit 072030b178 ("drm/amd: Disable
PSR-SU on Parade 0803 TCON") but reverted as commit 1e66a17ce5 ("Revert
"drm/amd: Disable PSR-SU on Parade 0803 TCON"") in favor of testing for
a new enough microcode (commit cd2e31a9ab ("drm/amd/display: Set minimum
requirement for using PSR-SU on Phoenix")).

As hangs are still happening specifically with this TCON, disable PSR-SU
again for it until it can be root caused.
