swiotlb: export swiotlb_dma_ops
For architectures that do not use per-device dma ops we need to export the dma_map_ops structure returned from get_arch_dma_ops(). Fixes: 10314e09 ("riscv: add swiotlb support") Signed-off-by: Christoph Hellwig <hch@lst.de> Reported-by: Andreas Schwab <schwab@suse.de>
