As a preparation to switch the DSA subsystem from using
of_find_net_device_by_node() to its more generic fwnode_
equivalent, the port's device structure should be updated
with its fwnode pointer, similarly to of_node - see analogous
commit c4053ef32208 ("net: mvpp2: initialize port of_node pointer").

This patch is required to prevent a regression before updating
the DSA API on boards that connect the mvpp2 port to switch,
such as Clearfog GT-8K or CN913x CEx7 Evaluation Board.

 	dev->dev.of_node = port_node;
+	dev->dev.fwnode = port_fwnode;

device_set_node() ?
