Sebastien Boeuf 03352f45f9 arch: Create ACPI IORT table
The virtual IOMMU exposed through virtio-iommu device has a dependency
on ACPI. It needs to expose the device ID of the virtio-iommu device,
and all the other devices attached to this virtual IOMMU. The IDs are
expressed from a PCI bus perspective, based on segment, bus, device and
function.

The guest relies on the topology description provided by the IORT table
to attach devices to the virtio-iommu device.
