Can we select IOMMU_DMA under IOMMU_SUPPORT instead? The only drivers
not using IOMMU_DMA are the arm32 ones, afaics.

If we could get rid of the arm32 exception, the IOMMU_DMA symbol could
also go away entirely and we handle it under IOMMU_SUPPORT instead. But
that is something for the future :)

Regards,

Joerg
