PATCH v2 1/1 doc: usb: ci-hdrc-usb2: Add property "mux-controls"
The chipidea usb controller may be connected, in some platforms, to an external mux to toggle between different usb ports for different roles (host and device).
The mux-controller property, if set, binds the chipidea usb controller with a mux for this use.
