[SCSI] qla2xxx: Retrieve board serial-number and description from VPD.

Browse source 
Recent ISPs have this information written at manufacturing time,
so use the information.  This also reduces future churn of the
qla_devtbl.h file contents, as the driver can now depend on the
information to be present in VPD.
