x86: remove map_single and unmap_single in struct dma_mapping_ops
This patch converts dma_map_single and dma_unmap_single to use map_page and unmap_page respectively and removes unnecessary map_single and unmap_single in struct dma_mapping_ops. This leaves intel-iommu's dma_map_single and dma_unmap_single since IA64 uses them. They will be removed after the unification.
