au1xxx-ide: fix MWDMA support
Always use "fast" MWDMA support and remove dma_{black,white}_list (they were based on completely bogus ->ide_dma_check implementation which didn't set neither the host controller timings nor the device for the desired transfer mode). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
