Subject: Decode configuration for the IDE part of the Triton chipset.  This
 includes a hack in the probe code: the 82371FB is a multifuction device, but
 doesn't properly set the configuration bit which indicates this.  So, we just
 hard-wire all 82371FBs as multifunction devices.

This does not actually make the bus-master IDE stuff work, although
if anyone wants to work on that, I have the databooks that tell
how to use it.
