aec62xx: no need to disable UDMA in ->init_hwif method for ATP850UF
* No need to disable UDMA in ->init_hwif method for ATP850UF (and since we now always tune PIO it will be disabled by ->set_pio_mode calls anyway). * Bump driver version. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
