* Add ->ftf_flags field to struct ide_taskfile
  and convert flags for TASKFILE ioctl to use it.

* Rename "flagged" taskfile flags:
  - IDE_TFLAG_FLAGGED -> IDE_FTFLAG_FLAGGED
  - IDE_TFLAG_FLAGGED_SET_IN_FLAGS -> IDE_FTFLAG_SET_IN_FLAGS
  - IDE_TFLAG_{OUT,IN}_DATA -> IDE_FTFLAG_{OUT,IN}_DATA

v2:
* Remember to fully update ide-h8300.c, scc_pata.c and tx493{8,9}ide.c
  (thanks to Stephen Rothwell for noticing).

There should be no functional changes caused by this patch.

This is IDE host driver for AT91 (SAM9, CAP9, AT572D940HF) Static Memory
Controller with Compact Flash True IDE Mode logic.

Driver have to switch 8/16 bit bus width when accessing Task Tile or Data
Register. Moreover some extra things need to be done when setting PIO mode.
Only PIO mode is used, hardware have no DMA support. If interrupt line is
connected through GPIO extra quirk is needed to cope with fake interrupts.
