[PATCH v7 0/8] virtio-iommu: Add ACPI support (Arm part + tests)

[Jean-Philippe Brucker]

Add ACPI support for virtio-iommu on the virt machine, by instantiating
a VIOT table. Also add the tests for the ACPI table.

Since last posting [1], I rebased onto v6.2.0-rc4. Note that v6 of this
series [2] only contained the table and x86 support, which have been
merged. Everything has now been reviewed and should be good to go.

* Patches 1-2 add the VIOT table for the virt machine
* Patches 3-4 are minor fixes
* Patches 5-8 add tests for the VIOT table. They contain the tests for
  q35 as well, which didn't make it last time because they depended on
  another fix that has now been merged.
