This function is the pendant of drm_of_find_panel_or_bridge() to remove a previously allocated panel_bridge. Given a specific port and endpoint it remove the panel bridge. Since drm_panel_bridge_remove() will check that bridge parameter is not NULL and is a real drm_panel_bridge and no a simple bridge it is safe to call it directly.
