[PATCH] ppc: fix #ifdef-s in mediabay driver (take 2)

* 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
