ide: add ide_deprecated_find_port() helper
* Factor out code for finding ide_hwifs[] slot from ide_register_hw() to ide_deprecated_find_port(). * Convert bast-ide, ide-cs and delkin_cb host drivers to use ide_device_add() instead of ide_register_hw() (while at it drop doing "ide_unregister()" loop which tries to unregister _all_ IDE interfaces if useable ide_hwifs[] slot cannot be find). This patch leaves us with only two ide_register_hw() users: - drivers/macintosh/mediabay.c - drivers/ide/ide.c Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
