[PATCH v2 05/16] usb: hub: Associate port@ fwnode with USB port device

[Chen-Yu Tsai <wenst@chromium.org>]

When a USB hub port is connected to a connector in a firmware node
graph, the port itself has a node in the graph.

Associate the port's firmware node with the USB port's device,
usb_port::dev. This is used in later changes for the M.2 slot power
sequencing provider to match against the requesting port.
