ANDROID: GKI: arm64: dma-mapping: add support for IOMMU mapper
On systems with IOMMUs, it's useful to handle IOMMU mappings in the dma-mapping layer. This is currently supported on arm but not arm64. Add support in arm64 by gratuitously lifting most of the IOMMU-related stuff from dma-mapping.c in arm. The original arm work was done by Marek Szyprowski in [4ce63fcd: "ARM: dma-mapping: add support for IOMMU mapper"].
