From: Gustavo Padovan gustavo.padovan@collabora.co.uk
exynos_dp_commit() was getting called twice by exynos encoder core, once inside the .enable() call and another time by .commit() itself.
The remove of the second call caused the wake of a bug, the operations orders inside exynos_dp_commit was wrong and we had to move exynos_dp_start_video() to be the last operation in there.
