[5/5] ARM64: dts: meson-gx-p23x-q20x: enable USB on P23x and Q20x boards

Commit Message

All four devices are only using the dwc3 controller. The actual ports
are provided by dwc3's internal USB hub.
The implementation on P230, P231 and Q201 seems identical: the USB VBUS
supply seems to be hard-wired, while on Q200 the USB VBUS is provided
by GPIOAO_5.
