Subject: [PATCH] pata_it8213: MWDMA0 is unsupported


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.

Verified with the documentation (similar case as with pata_efar).
