MWDMA0 timings cannot be met with the PIIX based controller programming interface.
This change should be safe as this is how we have been doing things in IDE it8213 host driver for years.
Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> --- Verified with the documentation (similar case as with pata_efar).
On top of patches from yesterday.
