drm/amd/display: Fix Panel Replay not update screen correctly
commit bd8a9576617439bdc907c9ce0875909aea4221cb upstream.
[Why]
In certain use case such as KDE login screen, there will be no atomic
commit while do the frame update.
If the Panel Replay enabled, it will cause the screen not updated and
looks like system hang.
[How]
Delay few atomic commits before enabled the Panel Replay just like PSR.
