[Impact] The cppc-cpufreq driver fails to initialize on ThunderX2 systems, which is used to communicate power configuration to firmware.
[Test Case] sudo modprobe cppc-cpufree || echo "Fail"
[Regression Risk] The fix consists of clean cherry-picks from upstream that are restricted to a single driver. Regressions would therefore be restricted to platforms that support ACPI CPPC power management.
