 - Revert a recent schedutil cpufreq governor change that introduced
   a performace regression on Pixel 6 (Sam Wu).

 - Fix amd-pstate driver initialization after running the kernel via
   kexec (Wyes Karny).

 - Turn amd-pstate into a built-in driver which allows it to take
   precedence over acpi-cpufreq by default on supported systems and
   amend it with a mechanism to disable this behavior (Perry Yuan).

 - Update amd-pstate documentation in accordance with the other changes
   made to it (Perry Yuan).
