s390/sparsemem: Provide phys_to_target_node() with CONFIG_NUMA
Add a trival phys_to_target_node() implementation which always returns 0 if
CONFIG_NUMA is enabled, since the s390 NUMA implementation only supports
node 0.
This is similar to memory_add_physaddr_to_nid() in order to avoid runtime
warnings.
