[PATCH] enhancement in drivers/scsi/ncr53c8xx.c

[Khalid Aziz]

When working with LVD SCSI bus, I have found it to be rather useful 
to know if the bus is operating in LVD or SE mode since the bus auto 
switches. All the info needed to print the bus mode is already there 
in ncr53c8xx driver. This patch simply adds appropriate printk to do 
that.
