OvmfPkg: PciHostBridgeLib: set RootBus->NoExtendedConfigSpace
In "OvmfPkg/PciHostBridgeDxe/PciRootBridgeIo.c", the
RootBridgeIoCheckParameter() function hard-codes the maximum offset for
the PCI config space as 0xFF (see the MAX_PCI_REG_ADDRESS macro), which
matches OVMF's 0xCF8 / 0xCFC config access method.
The "MdeModulePkg/Bus/Pci/PciHostBridgeDxe" driver abstracts away config
space access via the PciSegmentLib class, so it has to be informed
separately about the config space size.
