Subject: [PATCH] Revert "drm/amd/display: update DML2 policy
EnhancedPrefetchScheduleAccelerationFinal DCN35"

This reverts
commit 9dad21f910fc ("drm/amd/display: update DML2 policy EnhancedPrefetchScheduleAccelerationFinal DCN35")

[why & how]
The offending commit exposes a hang with lid close/open behavior. Both issues seem to be related to ODM 2:1 mode switching, so there is another issue generic to that sequence that needs to be investigated.
