FUJITA Tomonori 97d9800de9 IA64: fix swiotlb alloc_coherent for non DMA_64BIT_MASK devices 
Before the dma ops unification, IA64 always uses GFP_DMA for
dma_alloc_coherent like:

#define dma_alloc_coherent(dev, size, handle, gfp)	\
	platform_dma_alloc_coherent(dev, size, handle, (gfp) | GFP_DMA)

This GFP_DMA enforcement doesn't make sense for IOMMUs since they can
do address translation to give addresses that devices can access
to. The IOMMU drivers ignore the zone flag. However, this is still
necessary for swiotlb since it can't do address translation.

We don't always need to use GFP_DMA for swiotlb. We need GFP_DMA for
devices incapable of 64bit DMA.

This patch is sorta updated version of:
