* Replace incorrect CONFIG_BLK_DEV_IDE #ifdef in
check_media_bay() by CONFIG_MAC_FLOPPY one.
* Replace incorrect CONFIG_BLK_DEV_IDE #ifdef-s by
CONFIG_BLK_DEV_IDE_PMAC ones.
* check_media_bay() is used only by drivers/block/swim3.c
so make this function available only if CONFIG_MAC_FLOPPY
is defined.
* check_media_bay_by_base() and media_bay_set_ide_infos()
are used only by drivers/ide/ppc/pmac.c so so make these
functions available only if CONFIG_MAC_FLOPPY is defined.

Ben, IMO this patch is safe for 2.6.24 (assuming that it builds fine :),
otherwise I would like to ask for permission to merge it through IDE
tree since I have other pending IDE patches depending on this one.
