[SCSI] aic7xxx: expose the bus setting to sysfs
Read the transciever register and display in the host transport properties. I'm still not entirely sure what this does for multiple transciever adapters (like some 160 ones) however, I suspect it displays the transciever state of the switchable bus segment.
