drm/imx: parallel-display: put the bridge returned by drm_bridge_get_next_bridge()

Browse Source 
The bridge returned by drm_bridge_get_next_bridge() is refcounted. Put it
when done. We need to ensure it is not put before either next_bridge or
next_bridge_state is in use, thus for simplicity use a cleanup action.
