soc/intel/tigerlake: Enable TCSS XHCI device and define port aliases 

Enable the USB4 XHCI driver and remove the ACPI name entry from the
SOC level function.

Define aliases for the USB2/3 ports on north and south XHCI devices in
chipset.cb so they can be referenced in the mainboard devicetree.

BUG=b:151731851
TEST=define usb ports by reference in volteer devicetree and ensure
they get properties added in SSDT for both north and south XHCI device.
