tools/power turbostat: consolidate duplicate model numbers
Often a new processor gets a new model number, but from a turbostat point of view, it is the same as a previous model. Support duplicates with 1-line updates, rather than error-prone scattering of model #'s. Signed-off-by: Len Brown <len.brown@intel.com>
