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.
