    Rework PowerMac media-bay support in such way that instead of
    un/registering the IDE interface we un/register IDE devices:
    
    * Add ide_port_scan() helper for probing+registerering devices on a port.
    
    * Rename ide_port_unregister_devices() to __ide_port_unregister_devices().
    
    * Add ide_port_unregister_devices() helper for unregistering devices on a port.
    
    * Add 'ide_hwif_t *cd_port' to 'struct media_bay_info', pass 'hwif' instead
      of hwif->index to media_bay_set_ide_infos() and use it to setup 'cd_port'.
    
    * Use ide_port_unregister_devices() instead of ide_unregister()
      and ide_port_scan() instead of ide_register_hw() in media_bay_step().
    
    * Unexport ide_register_hw() and make it static.
    
    v2:
    * Fix build by adding <linux/ide.h> include to <asm-powerpc/mediabay.h>.
