spapr: Populate ibm,associativity-lookup-arrays correctly for non-NUMA
When NUMA isn't configured explicitly, assume node 0 is present for
the purpose of creating ibm,associativity-lookup-arrays property
under ibm,dynamic-reconfiguration-memory DT node. This ensures that
the associativity index property is correctly updated in ibm,dynamic-memory
for the LMB that is hotplugged.
