ec811a94c5 ata: start separating SATA specific code from libata-scsi.c 
Start separating SATA specific code from libata-scsi.c:

* un-static ata_scsi_find_dev()

* move following code to libata-sata.c:
  - SATA only sysfs device attributes handling
  - __ata_change_queue_depth()
  - ata_scsi_change_queue_depth()

* cover with CONFIG_SATA_HOST ifdef SATA only sysfs device
  attributes handling code and ATA_SHT_NCQ() macro in
  <linux/libata.h>
