ata: expose ncq_enable_prio sysfs attribute only on NCQ capable hosts
There is no point in exposing ncq_enable_prio sysfs attribute for devices on PATA and non-NCQ capable SATA hosts so: * remove dev_attr_ncq_prio_enable from ata_common_sdev_attrs[] * add ata_ncq_sdev_attrs[] * update ATA_NCQ_SHT() macro to use ata_ncq_sdev_attrs[] Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
