usb: typec: driver for Intel PMC mux control
The Intel PMC microcontroller on the latest Intel platforms
has a new function that allows configuration of the USB
Multiplexer/DeMultiplexer switches that are under the
control of the PMC.
The Intel PMC mux control (aka. mux-agent) can be used for
swapping the USB data role and for entering alternate modes,
DisplayPort or Thunderbolt3.
