arm64: dts: mediatek: mt8390-genio-700-evk: Enable ethernet

Enable ethernet on the Genio 700 EVK board. It has been tested to work
with speeds up to 1000Mbps.

[Cleaned up to pass dtbs_check, follow DTS style guidelines, and split
between mt8188 and genio700 commits, and addressed further feedback from
the mailing list]
