[PATCH 2.6][TRIVIAL] Update ide.txt documentation to current ide.c

[Maciej Soltysiak]

Hi,

this patches updates Documentation/ide.txt to reflect more options that
really are supported by the IDE driver (drivers/ide.c)

The patch despite the dirnames is versus 2.6.0-test3-bk8.

Please review and luckily apply.
Regards,
Maciej
