make check on a build with pci disabled revealed an interesting
inconsistency: We create a virtio-9p-ccw device, but the base
virtio-9p-device is in code that is not built for !pci.

If I remove the pci dependency for hw/9pfs/ and fsdev/, things look
fine (at least on s390x). We probably need a different dependency,
though.

virtio-9p maintainers, any suggestions?
