The current code was ignoring the end of update for all overlay planes, caring only for the primary plane update in case of pageflip. This change adds a change to start to check for pending updates for all planes through exynos_plane->pending_fb. At the start of plane update the pending_fb is set with the fb to be shown on the screen. Then only when to fb is already presented in the screen we set pending_fb to NULL to signal that the update was finished.
