amd-cppc has 2 operation modes: autonomous (active) mode and
non-autonomous (passive) mode.
In active mode, we don't need Xen governor to calculate and tune the cpu
frequency, while hardware built-in CPPC power algorithm will calculate the
runtime workload and adjust cores frequency automatically a
