Merge branches 'pm-devfreq' and 'pm-opp'

Browse Source 
Merge devfreq and OPP (Operating Performance Points) updates for 6.14:

 - Clean up the Exynos devfreq driver and devfreq core (Markus Elfring,
   Jeongjun Park).

 - Minor cleanups and fixes for OPP (Dan Carpenter, Neil Armstrong, Joe
   Hattori).

 - Implement dev_pm_opp_get_bw() (Neil Armstrong).

 - Expose OPP reference counting helpers for Rust (Viresh Kumar).

* pm-devfreq:
  PM / devfreq: exynos: remove unused function parameter
  PM / devfreq: event: Call of_node_put() only once in devfreq_event_get_edev_by_phandle()

* pm-opp:
  PM / OPP: Add reference counting helpers for Rust implementation
  OPP: OF: Fix an OF node leak in _opp_add_static_v2()
  OPP: fix dev_pm_opp_find_bw_*() when bandwidth table not initialized
  OPP: add index check to assert to avoid buffer overflow in _read_freq()
  opp: core: Fix off by one in dev_pm_opp_get_bw()
  opp: core: implement dev_pm_opp_get_bw
