Add a hub device and two USB devices, of which one has a combined node.
Note that we need to represent the serial ports as well -- consider
devices with multiple ports per interface; which one should serdev
use? Sibling devices can also be described this way (e.g. gpio@0), and
would need to use the same address size.
Also note that serial ports have a standardised node name in ePAPR.
