* 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.

SHWT value is used as address valid to -CSx assertion and -CSx to -DIOx
assertion setup time, and contrarywise, -DIOx to -CSx release and -CSx
release to address invalid hold time, so it actualy applies 4 times and
so constitutes -DIOx recovery time.  Check requirement of the recovery
time and cycle time.  Also check SHWT maximum value.

This is the driver for the Toshiba TX4938 SoC EBUS controller ATA mode.
It has custom set_pio_mode and some hacks for big endian.
