Merge branches 'pm-core', 'pm-sleep', 'pm-opp' and 'pm-tools'

Merge PM core changes, updates related to system sleep support,
operating performance points (OPP) changes and power management
utilities changes for 6.4-rc1:

 - Drop unnecessary (void *) conversions from the PM core (Li zeming).

 - Add sysfs files to represent time spent in a platform sleep state
   during suspend-to-idle and make AMD and Intel PMC drivers use them
   (Mario Limonciello).

 - Use of_property_present() for testing DT property presence (Rob
   Herring).

 - Add set_required_opps() callback to the 'struct opp_table', to make
   the code paths cleaner (Viresh Kumar).

 - Update the pm-graph siute of utilities to v5.11 with the following
   changes:
   * New script which allows users to install the latest pm-graph
     from the upstream github repo.
   * Update all the dmesg suspend/resume PM print formats to be able to
     process recent timelines using dmesg only.
   * Add ethtool output to the log for the system's ethernet device if
     ethtool exists.
   * Make the tool more robustly handle events where mangled dmesg or
     ftrace outputs do not include all the requisite data.

 - Make the sleepgraph utility recognize "CPU killed" messages (Xueqin
   Luo).

* pm-core:
  PM: core: Remove unnecessary (void *) conversions

* pm-sleep:
  platform/x86/intel/pmc: core: Report duration of time in HW sleep state
  platform/x86/intel/pmc: core: Always capture counters on suspend
  platform/x86/amd: pmc: Report duration of time in hw sleep state
  PM: Add sysfs files to represent time spent in hardware sleep state

* pm-opp:
  OPP: Move required opps configuration to specialized callback
  OPP: Handle all genpd cases together in _set_required_opps()
  opp: Use of_property_present() for testing DT property presence

* pm-tools:
  PM: tools: sleepgraph: Recognize "CPU killed" messages
  pm-graph: Update to v5.11
