I started off with this, but on devices with both USB Type-C and
(native) DisplayPort, it seemed much more reasonable to make the
distinction; and thereby get the outputs named "USB-n".

Similarly, it looks quite reasonable that the output on my laptop are
eDP-1, USB-1 and USB-2.


But, if this is not the way its intended to be used, feel free to pick
this together with the other patches.
