Log Message:
Enable Fast SCSI transfers for WD33C93B parts with appropriate input
clocks.

My Seagate ST32430N now sees about 50% greater throughput (about 97% as
fast as IRIX can push it). However, there appear to be other performance
issues with the driver as other disks perform significantly worse than they
should, with or without this change.
