ide: use ata_tf_protocols enums
* Add IDE_TFLAG_MULTI_PIO taskfile flag and set it for commands using multi-PIO protocol. * Use ata_tf_protocols enums instead of TASKFILE_* defines to denote command's protocol and then rename ->data_phase field to ->protocol. * Remove no longer needed <linux/hdreg.h> includes. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
