The SMMU is part of a larger IP block that's also a memory controller.
Having it in drivers/iommu would mean that we need to provide a
mechanism to synchronize between the two drivers. They also share a
number of data tables, so that would need to be shared somehow as well.
By keeping both in the same directory we don't have to expose any of
this publicly.
