soc/intel/xeon_sp: Locate PCI devices by Ven/Dev ID

Since the ACPI code is looking for VtdBars, that only appear on
Vtd devices, search for the Vtd device in devicetree.
With the previous commit the VtdBar is now exposed as a resource
on the Vtd device and thus can easily be accessed and used.

Drop the FSP HOB parsing and just use coreboot native functions.
Allows the code to work with multiple PCI segment groups.
