Dou Liyang 5f4cdac6bc arch/sparc/include/asm/topology_64.h: remove unused parent_node() macro
Commit a7be6e5a7f ("mm: drop useless local parameters of
__register_one_node()") removed the last user of parent_node().

The parent_node() macro in SPARC64 platform is unnecessary.

Remove it for cleanup.
