drm/sun4i: Unbind components before releasing DRM and memory
[ Upstream commit e02bc29b2cfa7806830d6da8b2322cddd67e8dfe ]
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 reserved memory after component unbind instead of
before to match reverse creation order.
Fixes: f5a9ed867c83 ("drm/sun4i: Fix component unbinding and component master deletion")
