Add a test with 6 nodes to exercise most interesting corner cases of SRAT
and HMAT generation including the new Generic Initiator and Generic Port
Affinity structures. More details of the set up in the following patch
adding the table data.

v3: Ensure we have recognizable values in the PCI devfn by
using a multifunction device. virtio-pci-rng doesn't support
multifunctional usage, so switch to pci-testdev for this purpose.
