ide: use do_rw_taskfile() in flagged_taskfile()
Based on the earlier work by Tejun Heo.
* Move setting IDE_TFLAG_LBA48 taskfile flag from do_rw_taskfile()
function to the callers.
* Add IDE_TFLAG_FLAGGED taskfile flag for flagged taskfiles coming
from ide_taskfile_ioctl(). Check it instead of ->tf_out_flags.all.
* Add IDE_TFLAG_OUT_DATA taskfile flag to indicate the need to load
IDE data register in ide_tf_load().
* Add IDE_TFLAG_OUT_* taskfile flags to indicate the need to load
particular IDE taskfile registers in ide_tf_load().
* Update do_rw_taskfile() and ide_tf_load() users to set respective
IDE_TFLAG_OUT_* taksfile flags.
* Add task_dma_ok() helper.
* Use IDE_TFLAG_FLAGGED taskfile flag to select HIHI mask in ide_tf_load().
* Use do_rw_taskfile() in flagged_taskfile().
* Remove no longer needed 'tf_out_flags' field from ide_task_t.
There should be no functionality changes caused by this patch.
