The atomic modesetting interfaces supports async commits that should be

It also serializes commits that needs to run on the same crtc, putting the
following commit to wait until the current one is finished.

fimd_update_plane() programs BUF_START[win] and during the update
BUF_START[win] is copied to BUF_START_S[win] (its shadow register)
and starts scanning out, then it raises a irq.

The fimd_irq_handler, in the case we have a pending_fb, will check
the fb value was copied to START_S register and finish the update
in case of success.

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.
