From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Subject: [PATCH] pata_it8213: add UDMA100 and UDMA133 support
Fixes IDE -> libata regression.
IDE's it8213 host driver has been supporting those modes (per official documentation) since the initial driver's merge on Feb 7 2007 (commit 9c6712c0 "ide: add it8213 IDE driver").
