    Taking inspiration from the existing arch/arm code, break out some
    generic functions to interface the DMA-API to the IOMMU-API. This will
    do the bulk of the heavy lifting for IOMMU-backed dma-mapping.

    Since associating an IOVA allocator with an IOMMU domain is a fairly
    common need, rather than introduce yet another private structure just to
    do this for ourselves, extend the top-level struct iommu_domain with the
    notion. A simple opaque cookie allows reuse by other IOMMU API users
    with their various different incompatible allocator types.
