ide: skip "VLB sync" if host uses MMIO
* Skip "VLB sync" in ata_{in,out}put_data() if host uses MMIO. * Use I/O ops directly in ata_vlb_sync() an drop no longer needed 'ide_drive_t *drive' argument. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
