[PATCH 5/5] arm64: dts: qcom: nord-ride-embedded: Enable USB ports

[Shawn Guo]

Wire up the board specific pieces for USB ports. Enable i2c9 and add the
three NXP PTN3222 eUSB2 repeaters (one per USB port) with their 1.8 V
supply and reset GPIOs on the PMIC GPIO expanders.

Add the onsemi FUSB15201 dual port Type-C controller at 0x50, with
its interrupt and pinctrl state on pmau0102_i gpio8. Both controller
ports are wired on this board, so describe two usb-c-connector
children and cross-link their HS and SS endpoints to the dwc3 HS
endpoint and the QMP combo PHY SS output of USB_0 and USB_1. Both
controllers therefore run in OTG mode with usb-role-switch.

USB_2 has no Type-C connector, so it is configured as a fixed host
port. Its VBUS is supplied by a fixed regulator gated by
pmau0102_h gpio3, kept always-on since nothing switches it at
runtime.
