powerpc: Update obsolete comments in setup_32.c about entry conditions
early_init() is called in-place before kernel relocation and using whatever MMU setup exists at the point the kernel is entered. machine_init() is called after relocation and after some initial mapping of PAGE_OFFSET has been established (typically using BATs on 6xx/7xx/7xxx processors or some form of bolted TLB on others).
