I'd like to see that ifdef go away, as discussed. I agree that just
#define pci_sriov_configure_simple NULL
should suffice. As Christoph points out, it's not going to compile if
people try to just invoke it directly.

I'd also *really* like to see a way to enable this for PFs which don't
have (and don't need) a driver. We seem to have lost that along the
way.
