Merge tag 'amd-pstate-v6.13-2024-12-11' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/superm1/linux
Merge amd-pstate driver fixes for 6.13-rc4 from Mario Liminciello:
"Fix a problem where systems without preferred cores were
misdetecting preferred cores.
Fix issues with with boost numerator handling leading to
inconsistently programmed CPPC max performance values."

cpufreq/amd-pstate: Store the boost numerator as highest perf again
