ide: use ide_legacy_device_add() for qd65xx (take 2)
* Add 'unsigned long config' argument to ide_legacy_device_add() for setting hwif->config_data. * Use ide_find_port_slot() instead of ide_find_port() in ide_legacy_device_add(). * Handle IDE_HFLAG_QD_2ND_PORT and IDE_HFLAG_SINGLE host flags in ide_legacy_device_add(). * Convert qd65xx host driver to use ide_legacy_device_add(). v2: * Update ali14xx, dtc2278, ht6560b and umc8672 host drivers. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
