arm64: remove DMA_ERROR_CODE
The dma alloc interface returns an error by return NULL, and the mapping interfaces rely on the mapping_error method, which the dummy ops already implement correctly. Thus remove the DMA_ERROR_CODE define. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Robin Murphy <robin.murphy@arm.com>
