ide: switch set_xfer_rate() to use REQ_TYPE_ATA_TASKFILE requests
Based on the earlier work by Tejun Heo. Switch set_xfer_rate() to use REQ_TYPE_ATA_TASKFILE requests and make ide_wait_cmd() static. There should be no functionality changes caused by this patch. Cc: Tejun Heo <htejun@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
