Pull power management fixes from Rafael Wysocki:
 "These fix problems related to frequency limits management in cpufreq
  that were introduced during the 5.3 cycle (when PM QoS had started to
  be used for that), fix a few issues in the OPP (operating performance
  points) library code and fix up the recently added haltpoll cpuidle
  driver.

  The cpufreq changes are somewhat bigger that I would like them to be
  at this stage of the cycle, but the problems fixed by them include
  crashes on boot and shutdown in some cases (among other things) and in
  my view it is better to address the root of the issue right away.

  Specifics:

   - Using device PM QoS of CPU devices for managing frequency limits in
     cpufreq does not work, so introduce frequency QoS (based on the
     original low-level PM QoS) for this purpose, switch cpufreq and
     related code over to using it and fix a race involving deferred
     updates of frequency limits on top of that (Rafael Wysocki, Sudeep
     Holla).

   - Avoid calling regulator_enable()/disable() from the OPP framework
     to avoid side-effects on boot-enabled regulators that may change
     their initial voltage due to performing initial voltage balancing
     without all restrictions from the consumers (Marek Szyprowski).

   - Avoid a kref management issue in the OPP library code and drop an
     incorrectly added lockdep_assert_held() from it (Viresh Kumar).

   - Make the recently added haltpoll cpuidle driver take the 'idle='
     override into account as appropriate (Zhenzhong Duan)"
