[PATCH] arm64: dts: qcom: monaco-arduino-monza: add USB-C controller and connector

[Loic Poulain]

Add the Cypress USB Type-C controller and associated connector.
The controller is connected over I2C12 and wired to the USB1 DWC3.
The USB-C connector routes both high-speed and super-speed signals.

Enable dual-role data and power over the USB-C connector.
