Subject: [PATCH] drm/bridge: cdns-dsi: Set bridge connector type

Set the bridge connector type to DRM_MODE_CONNECTOR_DSI to properly
identify the DSI connector in the display pipeline.

Without this, the bridge connector type defaults to
DRM_MODE_CONNECTOR_Unknown. Hence, to get correct bridge type set the
bridge connector type to DRM_MODE_CONNECTOR_DSI.
