Most architectures do not support non-coherent allocations and either define dma_{alloc,free}_noncoherent to their coherent versions or stub them out. Openrisc uses dma_{alloc,free}_attrs to implement them, and only Mips implements them directly. This patch moves the Openrisc version to common code, and handles the DMA_ATTR_NON_CONSISTENT case in the mips dma_map_ops instance. Note that actual non-coherent allocations require a dma_cache_sync implementation, so if non-coherent allocations didn't work on an architecture before this patch they still won't work after it.
