hw/riscv: Validate cluster and NUMA node boundary 

There are two RISCV machines where NUMA is aware: 'virt' and 'spike'.
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 has been associated with multiple NUMA
nodes.
