provided by lib/iommu_helper.c.

Changes in v8:
- use __phys_to_pfn and __pfn_to_phys.
Changes in v7:
- dma_mark_clean: empty implementation;
- in dma_capable use coherent_dma_mask if dma_mask hasn't been
allocated.
Changes in v6:
- check for dev->dma_mask being NULL in dma_capable.
Changes in v5:
- implement dma_mark_clean using dmac_flush_range.
Changes in v3:
- dma_capable: do not treat dma_mask as a limit;
- remove SWIOTLB dependency on NEED_SG_DMA_LENGTH.
