ide: add ide_tune_dma() helper
After reworking the code responsible for selecting the best DMA transfer mode it is now possible to add generic ide_tune_dma() helper. Convert some IDE PCI host drivers to use it (the ones left need more work). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
