Vincent Abriou 29d1dc62e1 drm/sti: atomic crtc/plane update
Better fit STI hardware structure.
Planes are no more responsible of updating mixer information such
as z-order and status. It is now up to the CRTC atomic flush to
do it. Plane actions (enable or disable) are performed atomically.
Disabling of a plane is synchronize with the vsync event.
