drm/amd/display: Enable reallow for idle on DCN35

Browse Source 
[Why]
It was previously disabled for stability purposes, but command
submission causes residency issues in IPS video playback.

[How]
Enable the disallow/reallow pattern back. There's additional checks
now in DMCUB that should make this safer stability wise.
