Stefano Stabellini 8746515d7f xen: Add __GFP_DMA flag when xen_swiotlb_init gets free pages on ARM 
Make sure that xen_swiotlb_init allocates buffers that are DMA capable
when at least one memblock is available below 4G. Otherwise we assume
that all devices on the SoC can cope with >4G addresses. We do this on
ARM and ARM64, where dom0 is mapped 1:1, so pfn == mfn in this case.

No functional changes on x86.
