Subject: [PATCH net 1/2] net: ti: am65-cpsw-nuss: Fix devlink warning on module removal

devlink_port_unregister() should be called after unregister_netdev()
so that the devlink_port->type is set to DEVLINK_PORT_TYPE_NOTSET
and avoids the below warning.

[   48.511030] WARNING: CPU: 2 PID: 683 at net/devlink/port.c:1077 devl_port_unregister+0x80/0xa8

CC: stable@...r.kernel.org # v6.6+
Fixes: 58356eb31d60 ("net: ti: am65-cpsw-nuss: Add devlink support")
