From commit a94e4f24 ("MIPS: init: Drop boot_mem_map") onwards,
add_memory_region() is handled by memblock_add()/memblock_reserve()
directly and all bootmem API should be converted to memblock API.
Otherwise it will lead to boot failure, especially in the NUMA case
because add_memory_region lose the node_id information.
