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[]
