Fair enough. However, since identify_machine is called before MMU_init and
<platform>_init is called in identify_machine, then it's reasonable that
the ppc_md structure is filled out by the time we hit MMU_init.

So, it seems reasonable that "identify_machine" remains the messy
function and MMU_init could be cleaned up somewhat.
