x86, NUMA: Initialize and use remap allocator from setup_node_bootmem()

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.
