Subject: [PATCH 1/3] memblock: let memblock_type_name know about physmem type

Since commit 70210ed950b5 ("mm/memblock: add physical memory list")
the memblock structure knows about a physical memory list.

memblock_type_name() should return "physmem" instead of "unknown" if
the name of the physmem memblock_type is being asked for.
