On some platforms, the Type-C plug orientation is given on a GPIO line.
Document this optional Type-C connector property, and take the
assumption an active level represents an inverted/flipped orientation.

Should this be a property of the connector or of the parent device node?
I mean, unlike usb-b-connector (where ID and Vbus can be simple GPIOs
nearly directly connected to the pins of the connector) for the USB-C
the orientation is not a connector's GPIO, but rather some additional
not elementary logic.
