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.
