Merge branches 'pm-cpufreq' and 'pm-cpuidle'

Merge cpufreq and cpuidle changes for 5.18-rc1:

 - Make the schedutil cpufreq governor use to_gov_attr_set() instead
   of open coding it (Kevin Hao).

 - Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the
   cpufreq longhaul driver (Rafael Wysocki).

 - Unify show() and store() naming in cpufreq and make it use
   __ATTR_XX (Lianjie Zhang).

 - Make the intel_pstate driver use the EPP value set by the firmware
   by default (Srinivas Pandruvada).

 - Re-order the init checks in the powernow-k8 cpufreq driver (Mario
   Limonciello).

 - Make the ACPI processor idle driver check for architectural
   support for LPI to avoid using it on x86 by mistake (Mario
   Limonciello).

 - Add Sapphire Rapids Xeon support to the intel_idle driver (Artem
   Bityutskiy).

 - Add 'preferred_cstates' module argument to the intel_idle driver
   to work around C1 and C1E handling issue on Sapphire Rapids (Artem
   Bityutskiy).

 - Add core C6 optimization on Sapphire Rapids to the intel_idle
   driver (Artem Bityutskiy).

 - Optimize the haltpoll cpuidle driver a bit (Li RongQing).

 - Remove leftover text from intel_idle() kerneldoc comment and fix
   up white space in intel_idle (Rafael Wysocki).
