memblock: move reserve_bootmem_range() to memblock.c and make it static
reserve_bootmem_region() is only called from
memmap_init_reserved_pages() and it was in mm/mm_init.c because of its
dependecies on static init_deferred_page().
Since init_deferred_page() is not static anymore, move
reserve_bootmem_region(), rename it to memmap_init_reserved_range() and
make it static.
Update the comment describing it to better reflect what the function
does and drop bogus comment about reserved pages in free_bootmem_page().
Update memblock test stubs to reflect the core changes.
