setup_node_bootmem() is taken from 64bit and doesn't use remap
allocator. It's about to be shared with 32bit so add support for it.
If NODE_DATA is remapped, it's noted in the debug message and node
locality check is skipped as the __pa() of the remapped address
doesn't reflect the actual physical address.
On 64bit, remap allocator becomes noop and doesn't affect the
behavior.

Move the generic 64bit NUMA init machinery from numa_64.c to numa.c.
* node_data[], numa_mem_info and numa_distance
* numa_add_memblk[_to](), numa_remove_memblk[_from]()
* numa_set_distance() and friends
* numa_init() and all the numa_meminfo handling helpers called from it
* dummy_numa_init()
* memory_add_physaddr_to_nid()
A new function x86_numa_init() is added and the content of
numa_64.c::initmem_init() is moved into it. initmem_init() now simply
calls x86_numa_init().
Constants and numa_off declaration are moved from numa_{32|64}.h to
numa.h.
This is code reorganization and doesn't involve any functional change.

Create numa_emulation.c and move all NUMA emulation code there. The
definitions of struct numa_memblk and numa_meminfo are moved to
numa_64.h. Also, numa_remove_memblk_from(), numa_cleanup_meminfo(),
numa_reset_distance() along with numa_emulation() are made global.
- v2: Internal declarations moved to numa_internal.h as suggested by
Yinghai.
