soc/intel/common/block/usb4: Add TCSS XHCI driver for SSDT generation

In order to generate ACPI entries for USB devices attached to the
USB4/TBT/TCSS/North XHCI device it needs to have a driver that will
enumerate static devices on the bus.  This driver does that and nothing
else.

BUG=b:151731851
TEST=boot on volteer and check for USB devices on _SB.PCI0.TXHC.RHUB
