scsi: smartpqi: Enable SATA NCQ priority in sysfs

Browse source

Add device attribute 'sas_ncq_prio_enable' to enable SATA NCQ priority
support and provide I/O priority in SCSI command and pass priority
information to controller firmware.

This device attribute works only when device has NCQ priority support and
controller firmware can handle I/Os with NCQ priority attribute.
