soc/intel/xeon_sp: Initial support for PCI multi segment groups

Add PCI enumeration support by reading the PCIeSegment reported in the
FSP HOB and add it when creating the PCI domain for each stack.

The PCI enumeration will be able to scan the additional PCI segment
groups and properly handle those devices.

TEST: Booted on ibm/sbp1 with multiple PCI segment groups enabled
      to ubuntu 22.04.
