The topdown is a model specific feature and only be available for the
big core.

We need to check if topdown is supported before doing the test.

The same check in the test_topdown_groups() may be used here as well.

  if ! perf stat -e '{slots,topdown-retiring}' true > /dev/null 2>&1
  then
    echo "Topdown sampling read test [Skipped event parsing failed]"
    return
  fi

Thanks,
Kan
