x86: dma_alloc_coherent sets gfp flags properly
Non real IOMMU implemenations (which doesn't do virtual mappings,
e.g. swiotlb, pci-nommu, etc) need to use proper gfp flags and
dma_mask to allocate pages in their own dma_alloc_coherent()
(allocated page need to be suitable for device's coherent_dma_mask).
This patch makes dma_alloc_coherent do this job so that IOMMUs don't
need to take care of it any more.
Real IOMMU implemenataions can simply ignore the gfp flags.
