    Reimplement suspend/resume support using sdev->manage_start_stop.
    
    * Device suspend/resume is now SCSI layer's responsibility and the
      code is simplified a lot.
    
    * DPM is dropped.  This also simplifies code a lot.  Suspend/resume
      status is port-wide now.
    
    * ata_scsi_device_suspend/resume() and ata_dev_ready() removed.
    
    * Resume now has to wait for disk to spin up before proceeding.  I
      couldn't find easy way out as libata is in EH waiting for the
      disk to be ready and sd is waiting for EH to complete to issue
      START_STOP.
    
    * sdev->manage_start_stop is set to 1 in ata_scsi_slave_config().
      This fixes spindown on shutdown and suspend-to-disk.
