pqos: Show L3CA/MBA COS definitions per L3 cluster on AMD and Hygon

AMD and Hygon Platform QoS allocation configuration is per L3 cluster
(or Core Complex - CCX). Each L3 cluster (CCX) has one L3 cluster ID
which is used for both CAT and MBA ids.

Show L3CA/MBA COS definitions per L3 cluster instead of per socket on
AMD and Hygon platforms. The output of "pqos -s" looks like:

  $ pqos -s
  L3CA/MBA COS definitions for L3 Cluster (or Core Complex) 0:
      L3CA COS0 => MASK 0xffff
      ...
      L3CA COS15 => MASK 0xffff
      MBA COS0 => 2048 available
      ...
      MBA COS15 => 2048 available
  L3CA/MBA COS definitions for L3 Cluster (or Core Complex) N:
  ...
