Current code assumes the max bus(0xFF) is under this P2P bridge and temporarily set it as subordinate bus. It may cause silicon hangs during PCI enumeration in some specific case. Instead, it should get the max bus number from the bus number resources returned from PCI_HOST_BRIDGE_RESOURCE_ALLOCATION.StartBusEnumeration() and set it as subordinate bus.
