ide: add drive->dma_mode field
Add dma_mode field to ide_drive_t matching dma_mode field used in struct ata_device. The validity of the field is restricted to ->dma_pio_mode method only currently in IDE subsystem. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
