Subject: [PATCH 1/8] dt-bindings: phy: qcom,qmp-usb3-dp: Add altmode/switch properties

The QMP block deals with orientation switching and altmode switching
between USB and DisplayPort. Add the necessary properties to the binding
to allow it to be connected to a TypeC controller and trigger these
operations.
