[SCSI] sd: update sd to use the new pm callbacks
[SCSI] sd: update sd to use the new pm callbacks

Update sd driver to use the callbacks defined in dev_pm_ops.

sd_freeze is NULL, the bus level callback has taken care of quiescing
the device so there should be nothing needs to be done here.
Consequently, sd_thaw is not needed here either.

suspend, poweroff and runtime suspend share the same routine sd_suspend,
which will sync flush and then stop the drive, this is the same as before.

resume, restore and runtime resume share the same routine sd_resume,
which will start the drive by putting it into active power state, this
is also the same as before.
