Merge branch 'pm-cpufreq'

Merge cpufreq fixes for 5.19-rc5, including ARM cpufreq fixes and the
following one:

 - Make amd-pstate enable CPPC on resume from S3 (Jinzhou Su).

* pm-cpufreq:
  cpufreq: Add MT8186 to cpufreq-dt-platdev blocklist
  cpufreq: pmac32-cpufreq: Fix refcount leak bug
  cpufreq: qcom-hw: Don't do lmh things without a throttle interrupt
  drivers: cpufreq: Add missing of_node_put() in qoriq-cpufreq.c
  cpufreq: amd-pstate: Add resume and suspend callbacks
