x86/dma: Remove dma_alloc_coherent_gfp_flags()
All dma_ops implementations used on x86 now take care of setting their own
required GFP_ masks for the allocation. And given that the common code
now clears harmful flags itself that means we can stop the flags in all
the IOMMU implementations as well.
