Add two API functions named vsp1_du_atomic_begin() and vsp1_du_atomic_flush() to signal the start and end of an atomic update. The vsp1_du_setup_rpf() function is renamed to vsp1_du_atomic_update() for consistency. With this new API, the driver will reprogram all modified inputs atomically before restarting the video stream.
