Implement the virtio-iommu driver following version 0.5 of the specification [1]. Previous version of this code was sent back in April [2], implementing the first public RFC. Since then there has been lots of progress and discussion on the specification side, and I think the driver is in a good shape now. The reason patches 1-3 are only RFC is that I'm waiting on feedback from the Virtio TC
