powerpc: converted embedded platforms to use new define_machine support
Removed platform_init usage on 83xx and 85xx and use define_machine and probe(). For now we always return true in the problem since you can only build for one specific board at a time. This is an artificial constraint. When we get ride of it we will need to update the Kconfig's for these sub-arch's and make the board's probe() functions actually do something.
