PATCH 1/1 arm64: dts: allwinner: pine-h64: Enable USB 3.0 host

On both Pine H64 models, there is one USB 3.0 host port directly connected to the SoC. The VBUS is shared with the other USB 2.0 ports. Unfortunately the DWC controller binding does not have a VBUS supply.

IIRC this is exactly the reason why it was never added. Adding it without vbus property is not a good strategy.

Or we could describe a full usb-a-connector with vbus-supply, which still doesn't do anything ATM. I plan on working on that in the future.
