In am65_cpsw_nuss_remove(), move the call to am65_cpsw_unregister_devlink()
after am65_cpsw_nuss_cleanup_ndev() to avoid triggering the
WARN_ON(devlink_port->type != DEVLINK_PORT_TYPE_NOTSET) in
devl_port_unregister(). Makes it coherent with usage in
m65_cpsw_nuss_register_ndevs()'s cleanup path.

Fixes: 58356eb31d60 ("net: ti: am65-cpsw-nuss: Add devlink support")
