    * 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.
