drm/amd/display: Fixed corruption on 4K tvs 



[WHY]
When on the desktop freesync is not enabled,
doing a frame stretch causes the TV to display
undesired output.

[HOW]
By changing the logic so that when ever fresync
is supported the TV is notified we are in fressync
instead on a non fresync state.
