powerpc/machdep: Define 'compatibles' property in ppc_md and use it
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.
