Benjamin Herrenschmidt b1923caa6e powerpc: Merge 32-bit and 64-bit setup_arch()
There is little enough differences now.

mpe: Add a/p/k/setup.h to contain the prototypes and empty versions of
functions we need, rather than using weak functions. Add a few other
empty versions to avoid as many #ifdefs as possible in the code.
