The chipset has a limitation in the number of address bits it
can generate. The graphics portion uses a specific mask of
40 or 48 bits depending on the generation. For audio, it's a bit
less of an issue, so just mark them as no-64bit for now.
Without this, it crashes on POWER machines which can use high bits
in the DMA address to distinguish between DMA windows.
