No, that _is_ wrong, and it will end up in a circular dependency,
because for UML_PCI we currently do FORCE_PCI and then we have PCI and
HAVE_PCI and it all messes up ... Which is all correct right now.

That still seems reasonable (why give the choice of selecting PCI after
having selected VFIO/virtio PCI), but then with !MMU it can't work, so
the pieces there just need to depend on MMU.
