The call to axienet_mdio_setup should not depend on whether "phy-node" pressents on the DT. Besides, since `lp->phy_node` is used if PHY is in SGMII or 100Base-X modes, move it into the if statement. And the next patch will remove `lp->phy_node` from driver's private structure and do an of_node_put on it right away after use since it is not used elsewhere.
