ieee1394: sbp2: enable auto spin-up for Maxtor disks

At least Maxtor OneTouch III require a "start stop unit" command after
auto spin-down before the next access can proceed.  This patch activates
the responsible code in scsi_mod for all Maxtor SBP-2 disks.

Maybe that should be done for all SBP-2 disks, but better be cautious.
