[PATCH 06/15] drm/amd/display: do not wait for vblank during pipe programming

[Stylon Wang]

From: Josip Pavic <Josip.Pavic at amd.com>

[Why]
Waiting for the vlbank every time a global sync update is requested,
including during full update flips, results in a stutter.

[How]
Do not wait for vblank during pipe programming.
