ANX7625 can be used to mux converted video stream with the USB signals
on a Type-C connector. Provide minimal Type-C support necessary for
ANX7625 to register the Type-C port device and properly respond to data
/ power role events from the Type-C partner.

Notes:
- I'm not 100% happy having Type-C code in the DRM subtree. Should I use
  AUX device and to move Type-C-related code to drivers/usb/typec?
