Investigate the git history to uncover when and why the VFIO
properties were introduced and update the models. This is mostly
targeting vfio-pci device, since vfio-plateform, vfio-ap and vfio-ccw
devices are simpler.
Organize the vfio-pci properties in topics. It would be great to have
a way to do the same for the output.
