scsi: libsas: Define NCQ Priority sysfs attributes for SATA devices
libata sysfs attributes cannot be used for libsas-managed SATA devices
because the ata_port location is different for libsas.
Defined sysfs attributes (visible for SATA devices only):
- /sys/block/sda/device/ncq_prio_enable
- /sys/block/sda/device/ncq_prio_supported
The newly defined attributes will pass the correct ata_port to libata
helper functions.
