net: mvpp2: initialize port of_node pointer
Without a valid of_node in struct device we can't find the mvpp2 port device by its DT node. Specifically, this breaks of_find_net_device_by_node(). For example, the Armada 8040 based Clearfog GT-8K uses Marvell 88E6141 switch connected to the &cp1_eth2 port: &cp1_mdio { ... switch0: switch0@4 { compatible = "marvell,mv88e6085"; ... ports { ... port@5 { reg = <5>; label = "cpu"; ethernet = <&cp1_eth2>; }; }; }; }; Without this patch, dsa_register_switch() returns -EPROBE_DEFER because of_find_net_device_by_node() can't find the device_node of the &cp1_eth2 device.
