Subject: [PATCH] tools/power turbostat: Add Elkhart Lake support

Elkhart Lake(TREMONT) succeed GOLDMONT, reuse the code.

Elkhart Lake does not support group turbo limit counter
register and might trigger failure in has_turbo_ratio_group_limits(),
so it is not applicable to reuse GOLDMONT cpuid in intel_model_duplicates().
