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.

powerpc: Make generic_calibrate_decr() the default ppc_md.calibrate_decr() is a mandatory item. Its nullity is never checked so it must be non null on all platforms. Most platforms define generic_calibrate_decr() as their ppc_md.calibrate_decr(). Have time_init() call generic_calibrate_decr() when ppc_md.calibrate_decr() is NULL, and remove default assignment from all machines.

powerpc: Move 32-bit probe() machine to later in the boot process This converts all the 32-bit platforms to use the expanded device-tree which is a pretty mechanical change. Unlike 64-bit, the 32-bit kernel didn't rely on platform initializations to setup the MMU since it sets it up entirely before probe_machine() so the move has comparatively less consequences though it's a bigger patch.
