This patch fixes the support by removing a check for phy_node, and adding a call to of_phy_connect_fixed_link(). Also set netdev parent device via SET_NETDEV_DEV() call, this is needed so that OF MDIO core could find a node pointer for a device. Plus, fix "if (IS_ERR(phydev))" check, in case of errors, of_phy_connect() returns NULL, not ERR_PTR as phy_connect().
