Bug Description

After upgrading to 5.19.0-31 (two of my systems) CPU driver changes to acpi-cpufreq. instead of amd_pstate.

This causes cpu to keep higher frequency and increased consumption.

```
with newer kernel also policy files for amd_pstate

Tried it on 2 Asus PN51-S1 systems with AMD Ryzen 7 5700U

I am currently staying at 5.19.0-29 as it is working better.

It gets disabled by commit ("cpufreq: amd-pstate: add amd-pstate driver parameter for mode selection").

Use kernel parameter "amd_pstate=passive" to enable it once again.

Isn't it strange to change behaviour on a Kernel, especially amd_pstate which is not loaded anymore. BUT intel_pstate is still.

shouldn't on a patch not to change this? it is really. Bad, how many users will suffer with their laptops, not understanding what is causing their battery drains.
