[PATCH] arm64: dts: allwinner: pine-h64: Enable USB 3.0 host

[Chen-Yu Tsai]

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.

Best regards,

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.
