x86, ia64: convert to use generic dma_map_ops struct
This converts X86 and IA64 to use include/linux/dma-mapping.h.
It's a bit large but pretty boring. The major change for X86 is
converting 'int dir' to 'enum dma_data_direction dir' in DMA mapping
operations. The major changes for IA64 is using map_page and
unmap_page instead of map_single and unmap_single.
