drm/dsi: Add routine to unregister a DSI device
A driver calling mipi_dsi_device_register_full() might want to remove the device once it's done. It might also require it in an error handling path in case something went wrong. Create mipi_dsi_device_unregister() for this purpose and use it within mipi_dsi_remove_device_fn() as it does the same thing.
