Now that iommufd does not rely on dma-iommu.c for any purpose. We can combine the dma-iommu.c iova_cookie and the iommufd_hwpt under the same union. This union is effectively 'owner data' and can be used by the entity that allocated the domain. Note that legacy vfio type1 flows continue to use dma-iommu.c for sw_msi and still need iova_cookie.
