drm: get drm_bridge_panel connector via helper 

The drm_connector created by drm_panel_bridge was accessed
via drm_panel.connector.
Avoid the detour around drm_panel by providing a simple get method.
This avoids direct access to the connector field in drm_panel in
the two users.

The change is done in preparation for removal of drm_panel.connector.

Update pl111 and tve200 to use the new helper.
