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.
