drm/sti: Use drm_atomic_helper_shutdown
drm_plane_helper_disable is a non-atomic drivers only function, and
will blow up (since no one passes the locking context it needs).
Atomic drivers which want to quiescent their hw on unload should
use drm_atomic_helper_shutdown() instead.
The sti cleanup code seems supremely confused:
- In the load error path it calls drm_mode_config_cleanup before it
stops various kms services like poll worker or fbdev emulation.
That's going to oops.
- The actual unload code doesn't even bother with the cleanup and just
leaks.
Try to fix this while at it.
