[PATCH v3 07/10] arm64: dts: uniphier: Add USB-device support for PXs3 reference board

[Kunihiko Hayashi]

PXs3 reference board can change each USB port 0 and 1 to device mode
with jumpers. Prepare devicetree sources for USB port 0 and 1.

This specifies dr_mode, pinctrl, and some quirks and removes nodes for
unused phys and vbus-supply properties.
