s390/sparsemem: Provide memory_add_physaddr_to_nid() with CONFIG_NUMA
virtio-mem uses memory_add_physaddr_to_nid() to determine the NID to use
for memory it adds.
We currently fallback to the dummy implementation in mm/numa.c with
CONFIG_NUMA, which will end up triggering an undesired pr_info_once():
Unknown online node for memory at 0x100000000, assuming node 0
On s390, we map all cpus and memory to node 0, so let's add a simple
memory_add_physaddr_to_nid() implementation that does exactly that,
but without complaining.
