[PATCH 12/12] dma-mapping: turn dma_cache_sync into a dma_map_ops method

After we removed all the dead wood it turns out only two architectures actually implement dma_cache_sync as a no-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
