On PowerNV platforms we always have 1:1 mapping between chip ID and firmware group id. Use the helper to convert firmware group id to node id instead of directly using chip ID as Linux node id.
NOTE: This doesn't have any functional change. On PowerNV platforms we continue to have 1:1 mapping between firmware group id and Linux node id. Reviewed-by: Gautham R.
