powerpc/dma: untangle vio_dma_mapping_ops from dma_iommu_ops
vio_dma_mapping_ops currently does a lot of indirect calls through dma_iommu_ops, which not only make the code harder to follow but are also expensive in the post-spectre world. Unwind the indirect calls by calling the ppc_iommu_* or iommu_* APIs directly applicable, or just use the dma_iommu_* methods directly where we can.
