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

Add a topology description to the virtio-iommu driver and enable x86 platforms. Since [v2] we have made some progress on adding ACPI support for virtio-iommu, which is the preferred boot method on x86. It will be a new vendor-agnostic table describing para-virtual topologies in a minimal format. However some platforms don't use either ACPI or DT for booting (for example microvm), and will
