[ Upstream commit 812af433038f984fd951224e8239b09188e36a13 ]
Current logic iterates over CPUID Fn8000001d leafs (Cache Properties)
to detect the last level cache, and derive the last-level cache ID.
However, this information is already available in the cpu_llc_id.
Therefore, make use of it instead.
