pata_marvell: Cable and reset fixes
There are two changes here. Firstly we switch to a cable detect method, secondly the old code forgot to call ata_std_prereset() but somehow managed to work anyway. Fix the missing call. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
