Add a driver for the ACPI VIOT table, which provides topology
information for para-virtual IOMMUs. Enable virtio-iommu on
non-devicetree platforms, including x86.

Since v3 [1] I fixed a build bug for !CONFIG_IOMMU_API. Joerg offered to
take this series through the IOMMU tree, which requires Acks for patches
1-3.

You can find a QEMU implementation at [2], with extra support for
testing all VIOT nodes including MMIO-based endpoints and IOMMU.
This series is at [3].
