The device tree file for rk3328-evb in the Linux kernel does not have gmac2io enabled. Instead, gmac2phy is enabled, but that is not supported in U-boot. Move the gmac2io related nodes to rk3328-evb-u-boot.dtsi to preserve the current functionality. When the device tree files are synced, gmac2phy should be marked as "broken" in -u-boot.dtsi files.
