Will you queue this yourself, or should I send it together with the zpci cleanup patches?

We want to compile the 9pfs code iff virtfs is enabled and a virtio transport is available (not only pci!). Let's make the generated CONFIG_VIRTFS statement depend on either CONFIG_VIRTIO_PCI or (new) CONFIG_VIRTIO_CCW. The Makefiles for fsdev/ and hw/9pfs/ can then depend on CONFIG_VIRTFS directly.
