arm64: dts: uniphier: Add USB-device support for PXs3 reference board
[ Upstream commit 19fee1a1096d21ab1f1e712148b5417bda2939a2 ]
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.
