[PATCH 01/19] dt-bindings: usb: Add thunderbolt-switch property

[Sven Peter]

The USB4/Thunderbolt host routers on Apple Silicon SoCs require cable
and mode details to be provided out-of-band by the Type-C port controller.
Add a thunderbolt-switch property next to the existing orientation and mode
switches which marks a node as handler of these notifications.
