enhancement in drivers/scsi/sym53c8xx.c

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 sym53c8xx driver. This patch simply adds appropriate printk to do that.
