The patch series removes PciExpressLib and enables CCIX port
as PCIe root on N1SDP.

V4:
- Remove PciExpressLib and use PciSegmentLib instead. More detailed explanation
  is included in the patch.

V3:
- The conditional logic in GetPciExpressAddress is made simple.
- Removed few more PCD entries that were unused.
- Removed hardcoded entries.

V2:
- Removed few PCDs entries that were not used.
- Migrated to latest version edk2-platform and validated the patches.

V1:
-  The PciExpressLib is updated to validate the PCIe addresses
  and introducing corresponding PCD entries.
- A custom PCI Segment library is adapted from SynQuacerPciSegmentLib
  and ported for N1Sdp.
- The root complex node info in PciHostBridge library is updated to
  include the CCIX port information.
