hw/arm: Validate cluster and NUMA node boundary
There are two ARM machines where NUMA is aware: 'virt' and 'sbsa-ref'.
Both of them are required to follow cluster-NUMA-node boundary. To
enable the validation to warn about the irregular configuration where
multiple CPUs in one cluster have been associated with different NUMA
nodes.
