Subject: [PATCH v8 3/3] arm64: dts: qcom: sm8750: Add USB support for SM8750 QRD platform

From: Wesley Cheng <wesley.cheng@....qualcomm.com>

Enable USB support on SM8750 QRD variant.  The current definition
will start the USB controller in peripheral mode by default until
dependencies are added, such as USB role detection.
