This indicates that any choice of a different swiotlb pools needs to
be hidden inside of ѕwiotlb. The dma mapping API already provides
swiotlb the addressability requirement for the device. Similarly we
already have a SWIOTLB_ANY flag that switches to a 64-bit buffer
by default, which we can change to, or replace with a flag that
allocates an additional buffer that is not addressing limited.
