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.
