Is these the COMPAQ HSV and MSA devices that need the spinup?

The qlogic driver conditionally sends a spinup for the
FO_NOTIFY_TYPE_SPINUP. AFAICT it is all or nothing since it is based on
the global variable qla_fo_params.FailoverNotifyType, so mixing arrays
where some require spinup and some don't could break it.

# grep FO_NOTIFY_TYPE_SPINUP *.[hc]
qla_cfg.c:      } else if (qla_fo_params.FailoverNotifyType ==
FO_NOTIFY_TYPE_SPINUP ||
qla_cfg.c:                      old_lp->fcport->notify_type ==
FO_NOTIFY_TYPE_SPINUP ){
qla_devtbl.h:   {"COMPAQ", "MSA1000", 2, FO_NOTIFY_TYPE_SPINUP, 
qla_devtbl.h:   {"COMPAQ", "HSV110 (C)COMPAQ", 4, FO_NOTIFY_TYPE_SPINUP,   
qla_devtbl.h:   {"HP", "HSV100", 4, FO_NOTIFY_TYPE_SPINUP,   
qla_fo.c:       if (qla_fo_params.FailoverNotifyType ==
FO_NOTIFY_TYPE_SPINUP ||
qla_fo.c:               new_lp->fcport->notify_type ==
FO_NOTIFY_TYPE_SPINUP ) {
qlfo.h:#define FO_NOTIFY_TYPE_SPINUP                  5
qlfo.h:#define FO_NOTIFY_TYPE_DEF                FO_NOTIFY_TYPE_SPINUP
qlfolimits.h:#define FO_NOTIFY_TYPE_SPINUP                    5
