Implement pcibios_sriov_{add|del}_vfs as empty functions. VF
creation will be triggered by the hotplug code.

And instead of having the arch suplply a no-op arch override I
think it would be better to have the config option just stub it
out in common code.

Or in fact maybe even a runtime flag in struct pci_dev.  Who knows
if all future s390 PCIe busses will have exactly the same behavior
or if we eventually get the standards compliant behvior back?
