x86, amd: Normalize compute unit IDs on multi-node processors
On multi-node CPUs we don't need the socket wide compute unit ID but the node-wide compute unit ID. Thus we need to normalize the value. This is similar to what we do with cpu_core_id. A compute unit is then identified by physical_package_id, node_id, and compute_unit_id.
