Implement the virtio-iommu driver, following specification v0.9 [1]. Since v4 [2] I fixed the issues reported by Eric, and added Reviewed-by from Eric and Rob. Thanks! I changed the specification to fix one inconsistency discussed in v4. That the device fills the probe buffer with zeroes is now a "SHOULD" instead of a "MAY", since it's the only way for the driver to know
