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.
