ide-cs: fix probing and add warm-plug support
* Fix probing by using ide_port_scan() and moving "retry loop" from ide_config() to idecs_register(). * Don't fail probe if there are no devices attached to a port. * Remove (now redundant) error message from ide_config(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
