commit 16dcbdef404f4e87dab985494381939fe0a2d456 upstream.

Add a drm_sysfs_connector_remove call when we destroy the panel to make
sure the connector node in sysfs gets deleted.

This is required for proper unload and re-load of this driver, otherwise
we will get a warning about a duplicate filename in sysfs.
