[PATCH 17/21] ARM: dma-mapping: use arch_sync_dma_for_{device,cpu}() internally

From: Arnd Bergmann The arm specific iommu code in dma-mapping.c uses the page+offset based __dma_page_cpu_to_dev()/__dma_page_dev_to_cpu() helpers in place of the phys_addr_t based arch_sync_dma_for_device()/arch_sync_dma_for_cpu() wrappers around the. In order to be able to move the latter
