One additional thought, I'm not sure that the driver should update on
vblank in this situation anyway. As one can see the fimd_update_plane()
call is triggered by a setcrtc ioctl, so AFAIK the update should happen
immediately.
My knowledge about FIMD is very limited, but I guess there is a way to
write directly without using the shadow registers.

Sure, I can do that!
