Subject: mm/memblock.c: move memblock_{add,reserve}_region into
 memblock_{add,reserve}

memblock_add_region() and memblock_reserve_region() do nothing specific
before the call of memblock_add_range(), only print debug output.

We can do the same in memblock_add() and memblock_reserve() since both
memblock_add_region() and memblock_reserve_region() are not used by
anybody outside of memblock.c and memblock_{add,reserve}() have the same
set of flags and nids.

Since memblock_add_region() and memblock_reserve_region() will be
inlined, there will not be functional changes, but will improve code
readability a little.
