tools/power turbostat: Support Elkhart Lake
From a turbostat point of view the Tremont-based Elkhart Lake is very similar to Goldmont, reuse the code of Goldmont. Elkhart Lake does not support 'group turbo limit counter' nor C3, adjust the code accordingly. Signed-off-by: Chen Yu <yu.c.chen@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
