x86, NUMA: Make 32bit use common NUMA init path

With both _numa_init() methods converted and the rest of init code
adjusted, numa_32.c now can switch from the 32bit only init code to
the common one in numa.c.

* Shim get_memcfg_*()'s are dropped and initmem_init() calls
  x86_numa_init(), which is updated to handle NUMAQ.

* All boilerplate operations including node range limiting, pgdat
  alloc/init are handled by numa_init().  32bit only implementation is
  removed.

* 32bit numa_add_memblk(), numa_set_distance() and
  memory_add_physaddr_to_nid() removed and common versions in
  numa_32.c enabled for 32bit.

This change causes the following behavior changes.

* NODE_DATA()->node_start_pfn/node_spanned_pages properly initialized
  for 32bit too.

* Much more sanity checks and configuration cleanups.

* Proper handling of node distances.

* The same NUMA init messages as 64bit.
