[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.
