xilinx: Fix mdio bus description for vck190-sc

Current behavior is that eth_phy_get_mdio_bus

Net:   FEC: can't find phy-handle

ZYNQ GEM: ff0b0000, mdio bus ff0b0000, phyaddr 0, interface sgmii
eth0: ethernet@ff0b0000

Net:
ZYNQ GEM: ff0b0000, mdio bus ff0b0000, phyaddr 0, interface sgmii
eth0: ethernet@ff0b0000
