[PATCH v8 0/7] Add virtio-iommu driver

Implement the virtio-iommu driver, following specification v0.12 [1].
Since last version [2] we've worked on improving the specification,
which resulted in the following changes to the interface:
* Remove the EXEC flag.
* Add feature bit for the MMIO flag.
* Change domain_bits to domain_range.

Given that there were small changes to patch 5/7, I removed the review
and test tags. Please find the code at [3].
