MdeModulePkg: PciHostBridgeDxe: don't assume extended config space
The "pc" ("pc-i440fx-*") machine types of QEMU don't support extended
config space. Accordingly, OVMF will use the following library instances
in connection with the core PciHostBridgeDxe driver:
BasePciSegmentLibPci [class: PciSegmentLib]
BasePciLibCf8 [class: PciLib]
BasePciCf8Lib [class: PciCf8Lib]
Add a new field to the PCI_ROOT_BRIDGE structure so that
RootBridgeIoCheckParameter() can catch config space offsets above 0xFF on
such old (emulated) platforms.
