    Tread carefully around DMA subregions.

    Not all platforms support it.

    - If we want to limit to 32-bit DMA, just use a known 32-bit DMA tag.
    - If we want to limit to >32-bit DMA, but the host only has a known
      32-bit DMA tag, then just use that anyway.
    - If we want to limit to >32-bit DMA, but the host doesn't support
      bus_dmatag_subregion, then just use the 32-bit DMA tag anyway.

    Gives powerpc, sparc a chance of working.
