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>.
