sparc: Use HAVE_MEMBLOCK_NODE_MAP

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.
