sparc: Remove no-op dma_4v_sync_single_for_cpu and dma_4v_sync_sg_for_cpu
Now sparc uses include/asm-generic/dma-mapping-common.h. pci_sun4v.c doesn't need to have no-op dma_4v_sync_single_for_cpu and dma_4v_sync_sg_for_cpu (dma-mapping-common.h does nothing if sync_{single|sg}_for_cpu hook is not defined). So we can remove them safely. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Tested-by: Robert Reif <reif@earthlink.net> Acked-by: David S.
