pata-rb532-cf: replace rb532_pata_finish_io()
Since the delay used internally is just the same as ata_sff_pause() uses, rb532_pata_finish_io() does exactly the same as ata_sff_pause() and thus can be replaced by the later one. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
