m68k: mm: fix node memblock init

Browse source 
[ Upstream commit c43e55796dd4d13f4855971a4d7970ce2cd94db4 ]

After pulling 5.7.0 (linux-next merge), mcf5441x mmu boot was
hanging silently.

memblock_add() seems not appropriate, since using MAX_NUMNODES
as node id, while memblock_add_node() sets up memory for node id 0.
