[PATCH v2 1/4] arm64: dts: qcom: nord: Add the USB controller nodes

[Bartosz Golaszewski]

Add the base nodes for the three DWC3 USB controllers. These carry only
the SoC-invariant properties and are disabled by default. The extension
for the embedded Nord variant and relevant board files will add the
platform resources and enable them.

USB_2 has no SuperSpeed PHY and no 'ss_phy_irq' on this SoC, so it is
capped to high-speed and told to use UTMI as its pipe clock.
