Add two test cases for VIOT, one on the q35 machine and the other on
virt. To test complex topologies the q35 test has two PCIe buses that
bypass the IOMMU (and are therefore not described by VIOT), and two
buses that are translated by virtio-iommu.

It isn't actually, I think an earlier version of the patch needed it.
I'll remove this.

Thanks,
