Tom Chung d6ed6d0d2a drm/amd/display: Fix video glitch while drag window in PSR-SU
[Why]
Dmub will cache the video position data during PSR-SU enable.
The dmub will use an outdated MPO video position if user try
to drag the video window and it will cause video glitch.

[How]
Disable the PSR-SU temporarily while user drag the video window.
The PSR-SU will be re-enabled after the video window is stable.
