Subject: [PATCH v3 7/8] arm64: dts: qcom: sc8280xp-crd: Add QMP to SuperSpeed graph

With support for the QMP combo phy to react to USB Type-C switch events,
introduce it as the next hop for the SuperSpeed lanes of the two USB
Type-C connectors, and connect the output of the DisplayPort controller
to the QMP combo phy.

This allows the TCPM to perform orientation switching of both USB and
DisplayPort signals.
