The FSP has a parameter to enable or disable the VTD feature
(Intel's Virtualization Technology for Directed I/O). In current header
files for FSP-S (Apollo Lake and Gemini Lake) this parameter is set to
disabled per default. Therefore, if the FSP was not modified via BCT,
this feature is most likely disabled on all mainboards.
Add a chip parameter so that VTD can be enabled on mainboard level in
devicetree and therefore this feature can be activated if needed.

GLK has a dedicated USB2 port that is used specifically for CNVi
BT. This requires that the ACPI tables define an additional USB 2 port
which results in _ADR for USB 3 ports being different for GLK than
APL.
This change splits the ports in xhci.asl into APL and GLK specific
ports.asl and selects the appropriate file based on
CONFIG_SOC_INTEL_GLK. It also adds support for returning HS09 for GLK
if ACPI name is requested for that port.

This reverts commit b82afce18a.
Reason for revert: This causes depthcharge to not boot due to TPM timeout errors. Because there is no wait after setting the debounce register, we lose data because the read-modify-write loses the interrupt status bit.
e.g., GPIO 5 sets debounce, without a wait. Then GPIO 9 has it's debounce set. Because the interrupt controller is masking the interrupt enable status bit, the read-modify-write for GPIO9 loses the interrupt enable status bit and it never gets set again. This causes the interrupt to never latch.
We should possibly make depthcharge set the interrupt enable status bit for latched GPIOs.
