dma/ia64: update ia64 machvecs, swiotlb.c
Change all ia64 machvecs to use the new dma_*map*_attrs() interfaces.
Implement the old dma_*map_*() interfaces in terms of the corresponding new
interfaces. For ia64/sn, make use of one dma attribute,
DMA_ATTR_WRITE_BARRIER. Introduce swiotlb_*map*_attrs() functions.
