arch_topology: Drop LLC identifier stash from the CPU topology

Since the cacheinfo LLC information is used directly in arch_topology,
there is no need to parse and store the LLC ID information only for
ACPI systems in the CPU topology.

Remove the redundant LLC ID from the generic CPU arch_topology
information.
