x86/AMD: Fix last level cache topology for AMD Fam17h systems

On AMD Fam17h systems, the last level cache is not resident in the
northbridge. Therefore, we cannot assign cpu_llc_id to the same value as
Node ID as we have been doing until now.

We should rather look at the ApicID bits of the core to provide us the
last level cache ID info.
