  dma-mapping: turn dma_cache_sync into a dma_map_ops method (2017-10-19 16:37:49 +0200)

----------------------------------------------------------------
A couple of dma-mapping updates:

 - turn dma_cache_sync into a dma_map_ops instance and remove
   implementation that purely are dead because the architecture
   doesn't support noncoherent allocations
 - add a flag for busses that need DMA configuration (Robin Murphy)

----------------------------------------------------------------
