soc/intel: Add support for USB ACPI code generation
To support generating USB devices in ACPI the platform needs to
know how to determine a device name for each USB port, and for
any root hubs that may be present.
Recent Intel platforms route all ports to an XHCI controller
through a root hub. This is supported by considering the root
hub to be USB port type 0, the USB 2.0 ports to be type 2, and
the USB 3.0 ports to be type 3.
This was tested with a Kaby Lake platform by adding entries to
the devicetree and checking the resulting SSDT.
