drm: Allow drivers to modify plane_state in prepare_fb/cleanup_fb
The drivers have to modify the atomic plane state during the prepare_fb
callback so they track allocations, reservations and dependencies for
this atomic operation involving this fb. In particular, how else do we
set the plane->fence from the framebuffer!
