From: Heyi Guo heyi.guo@linaro.org
This is to prepare for switching to generic PciHostBridge driver. We are going to create a PciHostBridgeLib instance for D0x and fetch PCI root bridge informance from PlatformPciLib, so we add Segment to PCI_ROOT_BRIDGE_RESOURCE_APPETURE along with other PCI resource information. Segment numbers are kept the same as ACPI MCFG.
