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
