Log Message:
Support the sq(4) interface on the Challenge S's IOPLUS mezzanine. This
requires us to configure the IOPLUS to use the appropriate DMA channel,
depending on what other expansion cards may be installed. Further, we need
to do a bit more configuration of the sq(4) DMA engine, which apparently
was formerly being configured properly by the PROM. Use the same values,
which appear to work fine.

Also, extend the gio_arb_config interface as needed.

NB: We're currently setting the IOPLUS board to long burst, but it may be
better to use realtime. This will require some experimentation.
