* Add IDE_TFLAG_IN_DATA taskfile flag to indicate the need of reading
IDE_DATA_REG in ide_end_drive_cmd().
Set the new flag in ide_taskfile_ioctl() if ->in_flags.b.data is set.
* Add IDE_TFLAG_FLAGGED_SET_IN_FLAGS taskfile flag to indicate the
need of modifying ->in_flags in ide_taskfile_ioctl().
Set the new flag in flagged_taskfile() and move the code modifying
->tf_in_flags to ide_taskfile_ioctl().
While at it remove the bogus comment: ->tf_in_flags (except .b.data)
have no effect on selection of registers to read.
* Remove no longer needed 'tf_in_flags' field from ide_task_t.
As the result we finally have the internals of HDIO_DRIVE_TASKFILE ioctl
separated from the core IDE code.
There should be no functionality changes caused by this patch.
