ieee1394: sbp2: enable auto spin-up for all SBP-2 devices

Browse Source 
This is a follow-up to patch "ieee1394: sbp2: enable auto spin-up for
Maxtor disks".  When I 'ejected' an OXUF922 based HDD from a Mac OS X
box, it was spun down by the Mac and did not spin up by itself when
attached to a Linux box right after that.  The first SCSI command that
required the bridge to access the drive ended in
sda:<6>sd 18:0:0:0: Device not ready: <6>: Current: sense key: Not Ready
    Additional sense: Logical unit not ready, initializing cmd. required

Therefore the flag which instructs scsi_mod to send START STOP UNIT with
START=1 ("make medium ready") after such a condition is now enabled
unconditionally for all FireWire storage devices.
