[PATCH v2 04/18] arm64: dts: rockchip: enable usb ports on Qnap-TS433

[Heiko Stuebner]

Enable usb controllers and phys and add regulator infrastructure for the
usb ports on the TS433.

Of course there are no schematics available for the device, so the
regulator information comes from the vendor-devicetree with unknown
accuracy.
