arm64: dts: uniphier: Add USB-device support for PXs3 reference board
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.
