[POWERPC] PS3: Repository probe cleanups
Repository updates: - Extract ps3_repository_find_bus() from ps3_repository_find_device(), as the storage driver needs it. - Make ps3_repository_find_device() return -ENODEV if a device is not found, just like if a bus is not found. - Add ps3_repository_read_vuart_sysmgr_port() and ps3_repository_read_vuart_av_port() to get vuart port info. - Add device enumeration routines ps3_repository_find_device() and ps3_repository_find_devices(). - Cleanup debug routines.
