cpufreq/amd-pstate: Fix prefcore rankings

Browse Source 
commit 50a062a762 ("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.
