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.
