msm: mdss: wait for ping pong during unblank kickoff
During panel unblank a kickoff is done to turn on the panel so that the
first update is not delayed. However since buffer sync and display
commit is not called on this, need to make sure that the update finishes
completely including the workqueue that signals the fences. Signaling
the sync fence can potentially cause timeline to be ahead and end up
signaling the acquire fences early leading to source tearing on command
mode panels.
