4f774c4a65 cpufreq: Reintroduce ready() callback
This effectively revert '4bf8e582119e ("cpufreq: Remove ready()
callback")', in order to reintroduce the ready callback.

This is needed in order to be able to leave the thermal pressure
interrupts in the Qualcomm CPUfreq driver disabled during
initialization, so that it doesn't fire while related_cpus are still 0.

30f3490978 More power management updates for 5.15-rc1
- Add new cpufreq driver for the MediaTek MT6779 platform called
    mediatek-hw along with corresponding DT bindings (Hector.Yuan).
 
  - Add DCVS interrupt support to the qcom-cpufreq-hw driver (Thara
    Gopinath).
 
  - Make the qcom-cpufreq-hw driver set the dvfs_possible_from_any_cpu
    policy flag (Taniya Das).
 
  - Blocklist more Qualcomm platforms in cpufreq-dt-platdev (Bjorn
    Andersson).
 
  - Make the vexpress cpufreq driver set the CPUFREQ_IS_COOLING_DEV
    flag (Viresh Kumar).
 
  - Add new cpufreq driver callback to allow drivers to register
    with the Energy Model in a consistent way and make several
    drivers use it (Viresh Kumar).
 
  - Change the remaining users of the .ready() cpufreq driver callback
    to move the code from it elsewhere and drop it from the cpufreq
    core (Viresh Kumar).
 
  - Revert recent intel_pstate change adding HWP guaranteed performance
    change notification support to it that led to problems, because
    the notification in question is triggered prematurely on some
    systems (Rafael Wysocki).
 
  - Convert the OPP DT bindings to DT schema and clean them up while
    at it (Rob Herring).

Pull more power management updates from Rafael Wysocki:
 "These are mostly ARM cpufreq driver updates, including one new
  MediaTek driver that has just passed all of the reviews, with the
  addition of a revert of a recent intel_pstate commit, some core
  cpufreq changes and a DT-related update of the operating performance
  points (OPP) support code.

  Specifics:

   - Add new cpufreq driver for the MediaTek MT6779 platform called
     mediatek-hw along with corresponding DT bindings (Hector.Yuan).

   - Add DCVS interrupt support to the qcom-cpufreq-hw driver (Thara

b3beca7618 cpufreq: Remove ->resolve_freq()
Commit e3c0623608 ("cpufreq: add cpufreq_driver_resolve_freq()")
introduced this callback, back in 2016, for drivers that provide the
->target() callback.

The kernel hasn't seen a single user of it in the past 5 years and
it is not likely to be used any time soon.

Remove it for now.
