msm: mdss: flush timing after splash done for video panel 



During continuous splash handoff the pipes are unstaged and the
timing engine is being turned off. But this change is not
being flushed. Right after that we release the splash memory
and this sometimes causes a memory fault. This change adds
the necessary flush.
