[PATCH v7 1/4] arm64: dts: qcom: sm8750: Add USB support to SM8750 SoCs

[Krishna Kurapati <krishna.kurapati@oss.qualcomm.com>]

From: Wesley Cheng <quic_wcheng@quicinc.com>

Add the base USB devicetree definitions for SM8750 platforms.  The overall
chipset contains a single DWC3 USB3 controller (rev. 200a), SS QMP PHY
(rev. v8) and M31 eUSB2 PHY.  The major difference for SM8750 is the
transition to using the M31 eUSB2 PHY compared to previous SoCs.

Enable USB support on SM8750 MTP and QRD variants. SM8750 has a QMP combo
PHY for the SSUSB path, and a M31 eUSB2 PHY for the HSUSB path.
