Pull power management updates from Rafael Wysocki:
"This time, the most visible part are the ACPI CPPC updates from
Christian Loehle, including CPPC cpufreq driver changes, even though
updates of cpufreq drivers proper are still the largest topic group.
However, the updates of cpufreq drivers depend on the ACPI CPPC
updates, so they should really be counted together and that is well
over 1/2 of the total commit count.
Interestingly enough, almost all of the updates included here are
fixes or cleanups, with some new feature support in the amd-pstate
cpufreq driver and IPQ9650 support in the qcom-nvmem cpufreq driver.
The runtime PM documentation improvements from Brian Norris can also
be mostly regarded as fixes, but a new kunit test goes along with
them.

- Fix multiple issues related to input validation, synchronization,
access safety, memory layout and register field validation, and
error handling in the ACPI CPPC library (Christian Loehle and Sumit
Gupta)
