Subject: [PATCH net-next v3 07/12] nfp: Implement ndo_get_port_parent_id()
NFP only supports SWITCHDEV_ATTR_ID_PORT_PARENT_ID, which makes it a
great candidate to be converted to use the ndo_get_port_parent_id() NDO
instead of implementing switchdev_port_attr_get().
Since NFP uses switchdev_port_same_parent_id() convert it to use
netdev_port_same_parent_id().
