For dma mappings done with dma_map_sg() calls, dma_sync_sg* calls are required in order to make sure that caches for all the scattered addresses are synced. Using dma_sync_single* call for syncing caches can access address which is not mapped by dma_sync_sg() and cause kernel exceptions. Fix this by using correct cache sync calls for appropriate dma mapping APIs.
