powerpc/machdep: Define 'compatible' property in ppc_md and use it
Most probe functions do nothing else than checking whether
the machine is compatible to a given string.
Define that string 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.
