[ Upstream commit fd604ae6c261c5a56bb977ae99f875bbd7264a3f ]
commit 50a062a76200 ("cpufreq/amd-pstate: Store the boost numerator as highest perf again") updated the value stored for highest perf to no longer store the highest perf value but instead the boost numerator.
This is a fixed value for systems with preferred cores and not appropriate for use ITMT rankings. Update the value used for ITMT rankings to be the preferred core ranking.
