OvmfPkg/PlatformBootManagerLib: Handle the absence of PCI bus on Xen PVH
When running in a Xen PVH guest, there's nothing to do in
PciAcpiInitialization() because there isn't any PCI bus. When the Host
Bridge DID isn't recognised, simply continue. (The value of
PcdOvmfHostBridgePciDevId would be 0 because it isn't set.)
