Introduce a binding which represents a component that can control the
routing of USB Type-C data lines as well as address data line
orientation (based on CC lines' orientation).

+description:
+  A USB Type-C switch represents a component which routes USB Type-C data
+  lines to various protocol host controllers (e.g USB, VESA DisplayPort,
+  Thunderbolt etc.) depending on which mode the Type-C port, port partner
+  and cable are operating in. It can also modify lane routing based on
+  the orientation of a connected Type-C peripheral.
