dma: swiotlb: pass mapping attributes by reference

Browse source

Change swiotlb_tbl_map_single() to take the DMA mapping attributes by
reference and update the direct callers accordingly.

This is a preparatory change for a follow-up patch which updates the
attributes based on the selected swiotlb pool. Keeping the signature change
separate makes the follow-up patch easier to review.

No functional change in this patch.
