intel-iommu: make dma mapping functions static
The dma ops unification enables X86 and IA64 to share intel_dma_ops so we can make dma mapping functions static. This also remove unused intel_map_single(). Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Ingo Molnar <mingo@elte.hu>
