ide: ide_start_power_step() fix WRT disabling DMA
* Do the same thing as probe_hwif() and always disable DMA so chipset DMA enabled bit gets cleared (if the drive doesn't support DMA ide_set_dma() won't try to tune it anyway). * Add TODO comment about respecting ->using_dma setting. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
