drm/tilcdc: panel: fix dangling sysfs connector node
commit e396900e649b0af31161634d87fe37076f46c12b 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 as a
module. Without this, we would get a warning at re-load time like so:
