sparc doesn't access early_node_map[] directly and enabling
HAVE_MEMBLOCK_NODE_MAP is trivial - replacing add_active_range() calls
with memblock_set_node() and selecting HAVE_MEMBLOCK_NODE_MAP is
enough.
-v2: Use select in Kconfig instead as suggested by Sam Ravnborg.

Acked-by added and select used in Kconfig instead.
Thanks.
