Add support for multiple IOMMU indexes to the IOMMU notifier APIs. When initializing a notifier with iommu_notifier_init(), the caller must pass the IOMMU index that it is interested in. When a change happens, the IOMMU implementation must pass memory_region_notify_iommu() the IOMMU index that has changed and that notifiers must be called for. IOMMUs which support only a single index don't need to change. Callers which only really support working with IOMMUs with a single index can use the result of passing MEMTXATTRS_UNSPECIFIED to memory_region_iommu_attrs_to_index().
