I don't think it makes sense to have a stub for that - AFAICS it should
only ever be called form arch code with an inherent "select IOMMU_DMA"
(much like the stuff which isn't stubbed currently).
Otherwise, I'm about 97% sure the rest of the move looks OK - thanks for
splitting things up.
arm64 only selects IOMMU_DMA if IOMMU_SUPPORT is selected, which can
be disabled. So to keep some (unusual) arm64 configs compiling we'll need
the stub..
