Current users of this code will be arm and arm64, but later other archs can start utilizing this as well. Based on these discussion there has been work going on to refactor common arch independent code of arm iommu's dma-mapping to lib/iommu-helper.c [2]. Since now dma_iommu_mapping stuff will be arch independent, so it make sense to move out struct dma_iommu_mapping *mapping variable from arch/arm/*/device.h to include/linux/device.h as a first step [3].
