After we removed all the dead wood it turns out only two architectures actually implement dma_cache_sync as a real op: mips and parisc. Add a cache_sync method to struct dma_map_ops and implement it for the mips defualt DMA ops, and the parisc pa11 ops. Note that arm, arc and openrisc support DMA_ATTR_NON_CONSISTENT, but never provided a functional dma_cache_sync implementations, which seems somewhat odd.
