Tom Chung 34d66bc7ff drm/amd/display: Fix Xorg desktop unresponsive on Replay panel
[WHY & HOW]
IPS & self-fresh feature can cause vblank counter resets between
vblank disable and enable.
It may cause system stuck due to wait the vblank counter.

Call the drm_crtc_vblank_restore() during vblank enable to estimate
missed vblanks by using timestamps and update the vblank counter in
DRM.

It can make the vblank counter increase smoothly and resolve this issue.
