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.
