[PATCH 16/27] drm/amd/display: Fix DRR Enable on Desktop

Fri Jun 9 20:11:29 UTC 2017
From: Amy Zhang <Amy.Zhang at amd.com>
- Block PSR in Full screen apps to prevent incorrect static screen curser events
- Reprogram static screen events when update freesync state
- Program static ramp variable active after other values are programmed
- Correct wrong assigning of the nominal and current vcount
