The alias for PHY nodes here is: The ethernet has two kind of PHY interface, one is SGMII, and the other is RGMII, The selection is done by the reset configuration word(RCW), so Phy-handle properties should be change properly to reflecting the PHY interface selection. This is done by fixing up dtb in u-boot before booting the kernel. Thus the alias for PHY nodes is added here for fdt finding the PHY nodes easily.
