Most probe functions that do not use the 'compatible' string do nothing else than checking whether the machine is compatible with one of the strings in a NULL terminated table of strings. Define that table of strings in ppc_md structure and check it directly from probe_machine() instead of using ppc_md.probe() for that. Keep checking in ppc_md.probe() only for more complex probing. All .compatible could be replaced with a single element NULL terminated list but that's not worth the churn. Can be do incrementaly in follow-up patches.
