Subject: [PATCH 1/7] dt-bindings: phy: qcom,sc8280xp-qmp-usb43dp: Add ports and orientation-switch

The QMP combo phy can be connected to a TCPM, a USB controller and a
DisplayPort controller for handling USB Type-C orientation switching
and propagating HPD signals.

Extend the binding to allow these connections to be described.
