rockchip: dts: rk3328-evb: Move gmac2io related nodes to -u-boot.dtsi

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.
