As a preparation patch to extend MDIO capabilities in the ACPI world,
introduce fwnode_mdiobus_register_device() to register non-PHY
devices on the mdiobus.

While at it, also use the newly introduced fwnode operation in
of_mdiobus_phy_device_register().

...

 static int of_mdiobus_register_device(struct mii_bus *mdio,
 				      struct device_node *child, u32 addr)
 {

+	return fwnode_mdiobus_register_device(mdio, of_fwnode_handle(child), addr);
 }

Since it's static one-liner you probably may ger rid of it completely.
