[PATCH 2/3] arm64: dts: qcom: monaco-monza-som: Enable USB0 DRD mode

[Akash Kumar]

Enable USB0 dual-role mode on monza SOM using the Cypress CYPD6129 UCSI
controller.

Switch the controller node to I2C12, configure the required pinctrl and
interrupt settings, and wire the USB2/USB3 endpoints for the USB-C
connector.
