drm/amd/display: Disable panel replay by default for now 

Panel replay was enabled by default in commit 5950efe2
("drm/amd/display: Enable Panel Replay for static screen use case"), but
it isn't working properly at least on some BOE and AUO panels.  Instead
of being static the screen is solid black when active.  As it's a new
feature that was just introduced that regressed VRR disable it for now
so that problem can be properly root caused.
