init: fold build_all_zonelists() and page_alloc_init_cpuhp() to mm_init()

Both build_all_zonelists() and page_alloc_init_cpuhp() must be called
after SMP setup is complete but before the page allocator is set up.

Still, they both are a part of memory management initialization, so move
them to mm_init().
