[SCSI] pm8001: remove pm8001_slave_{alloc|configure}
libsas handles: 1/ limiting ata scanning to lun0 2/ changes to /sys/block/<sdX>/device/queue_depth for ata devices libata handles turning off ncq globally via kernel command line (libata.force=noncq) or sysfs (echo 1 > /sys/block/<sdX>/device/queue_depth). A lldd specific compile option is not necessary. Cc: Jack Wang <jack_wang@usish.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
