[stonking][PATCH 2/3] cpufreq/amd-pstate: Add EPP tunings for Zen6 client platforms

[Yo-Jung Leo Lin (AMD)]

From: "Mario Limonciello (AMD)" <superm1 at kernel.org>

BugLink: https://bugs.launchpad.net/bugs/2167558

Zen6 client platforms perform better with individual tunings for
different core types.  Add initial EPP tuning values for those
platforms.
