    IOMMU: move inclusion point of asm/iommu.h
    
    In preparation of allowing inline functions in asm/iommu.h to
    de-reference struct struct iommu_ops, move the inclusion downwards past
    the declaration of that structure. This in turn requires moving the
    struct domain_iommu declaration, as it requires struct arch_iommu to be
    fully declared beforehand.
