Nevertheless I think this doesn't go quite far enough - this internal index,
to be helpful, would need associating back to the respective firmware data.
What iommu_alloc() logs is not only limited to verbose mode, but also doesn't
include the index. I think something need doing there, and then we need to be
more consistent throughout to include the IOMMU index in log messages
pertaining to a particular IOMMU.
