[PATCH v1] drm/i915/selftests: Correct frequency handling in RPS power measurement

From: Sk Anirban <sk.anirban at intel.com>
Fix the frequency calculation by ensuring it is adjusted
only once during power measurement. Update live_rps_power test
to use the correct frequency values for logging and comparison.
