A driver calling mipi_dsi_device_register_full might want to unregister
the device once it's done. It might also require it in an error handling
path in case something didn't go right.
Create mipi_dsi_device_unregister for this purpse, use it within
mipi_dsi_remove_device_fn as it does the same thing.
