virtio-iommu-pci: Add virtio iommu pci support
This patch adds virtio-iommu-pci, which is the pci proxy for
the virtio-iommu device.
Currently non DT integration is not yet supported by the kernel.
So the machine must implement a hotplug handler for the
virtio-iommu-pci device that creates the device tree iommu-map
bindings as documented in kernel documentation:
