arm: dts: mediatek: add USB/PHY nodes for Genio 520/720

Add USB and PHY nodes for USB support on Genio 520/720 EVKs.

The devicetree hasn't been accepted upstream yet, so this comes from the
latest submission [1]. Some power domain and reset references have been
left out to minimize what we need to add at this time since U-Boot
doesn't need them.
