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.
No functional changes on x86.

This commit message must explain why the PFNs (IPAs)

Chen,
could you please try the patch below in your repro scenario?
I have only build tested it.

Make sure

This should definitely be done only on ARM and ARM64, as on x86 PVH
assumes the presence of an IOMMU. We need an ifdef.

Also we need to figure out a way to try without GFP_DMA in case no
