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.
