Currently the DSI driver has two separate paths: one if the next device in a chain is a bridge and another one if the panel is connected directly to the DSI host.
The later functionality is already suppurted by the panel-bridge driver, which wraps drm panel into the drm bridge instance. Using it will remove the need for special handling of drm_panel and drm_connector inside the DSI driver. With these patches in all cases the DSI driver will see the chain bridges which either support bridge-connector or allocate the connector on their own.
