[PATCH 01/13] add map/unmap_single_attr and map/unmap_sg_attr to struct dma_mapping_ops

[FUJITA Tomonori]

This adds map/unmap_single_attr and map/unmap_sg_attr to struct
dma_mapping_ops. This enables us to move the dma operations in struct
ia64_machine_vector to struct dma_mapping_ops.

Note that we will remove map/unmap_sg and map/umap_single.

This is a preparation of struct dma_mapping_ops unification.
