[PATCH 3/3] drm/fsl-dcu: disable outputs before unloading driver

[Stefan Agner]

Make sure that all outputs are disabled before unloading the DRM
driver. Otherwise vblank handling is not shut down properly and
warnings such as this appear:
WARNING: CPU: 0 PID: 540 at drivers/gpu/drm/drm_irq.c:339 drm_vblank_cleanup+0x5c/0x94
