I've added a new 'channel' keyword to config's 'scsi' interface
attribute, so you can specify which channel of multi-channel SCSI
controllers to attach SCSI busses to.

Right now, as far as i know that only matters for the aic7xxx family
of chips (which use the ahc driver, i believe), but i thought i'd tell
you all about it, anyway.


You can nail down the channel a scsibus will attach to by saying
something like:

	scsibus0 at ahc0 channel 1

If you don't specify the channel (or say "channel ?" to wildcard it),
any channel provided by the SCSI controller will match.  Devices which
only provide a single channel effectively provide it as number 0 (but
you don't need to worry about them, really).
