[PATCH] drm/sun4i: Unbind components before releasing DRM and mem at master unbind

[Paul Kocialkowski]

Our components may still be using the DRM device driver (if only to
access our driver's private data), so make sure to unbind them before
the final drm_dev_put.

Also release our resserved memory adter unbind to match reverse
creation order.
