[PATCH 4/5] arm64: dts: qcom: nord-rrd: Enable USB ports

[Shawn Guo]

Describe the RRD USB topology. Enable i2c9 and add the two NXP PTN3222
eUSB2 repeaters for USB_0 and USB_1, supplied from vreg_l3l_1p8 and a new
fixed 3.3 V pre-regulator, and reset through pmau0102_i GPIOs 9 and 10.

Add the onsemi FUSB15201 Type-C controller at 0x50 with its interrupt and
pinctrl state on pmau0102_i gpio8. Unlike RIDE, only port A of
the controller is wired on this board, to USB_0, so a single
usb-c-connector is described and port B is left out. USB_0 is configured
for OTG with usb-role-switch and its HS and SS endpoints are linked to
the dwc3 HS endpoint and the QMP combo PHY SS output.

USB_1 is a fixed host port feeding an on-board Genesys Logic GL3590 USB
3.1 hub. Add the HS and SS hub pair as children of USB_1, linked with
peer-hub, with the HS half reset via TLMM GPIO 170 and the SS half
additionally supplied by a fixed 1.2 V rail.
