Add a helper function that allow regulator consumers to allow low-level
HW access, in order to enable/disable regulator in atomic context.

The use-case for RZ/G2L SoC is to enable VBUS selection register based
on vbus detection that happens in interrupt context.

platform_pci_wakeup_init() was removed by d2e5f0c16ad6 ("ACPI / PCI: Rework
the setup and cleanup of device wakeup") but was still mentioned in the
documentation.

Update the doc to refer to pci_acpi_setup(), which does the equivalent
work.

Merge cpufreq changes for 6.9-rc1:

 - Enable preferred core support in the amd-pstate cpufreq driver (Meng
   Li).

 - Fix min_perf assignment in amd_pstate_adjust_perf() and make the
   min/max limit perf values in amd-pstate always stay within the
   (highest perf, lowest perf) range (Tor Vic, Meng Li).

 - Change default transition delay in cpufreq to 2ms (Qais Yousef).

 - Drop long-unused cpudata::prev_cummulative_iowait from the
   intel_pstate cpufreq driver (Jiri Slaby).

 - Allow intel_pstate to assign model-specific values to strings used in
   the EPP sysfs interface and make it do so on Meteor Lake (Srinivas
   Pandruvada).

 - Remove references to 10ms minimum sampling rate from comments in the
   cpufreq code (Pierre Gondois).

 - Prevent scaling_cur_freq from exceeding scaling_max_freq when the
   latter is an inefficient frequency (Shivnandan Kumar).

 - Honour transition_latency over transition_delay_us in cpufreq (Qais
   Yousef).

 - Stop unregistering cpufreq cooling on CPU hot-remove (Viresh Kumar).

 - General enhancements / cleanups to ARM cpufreq drivers (tianyu2,
   Nícolas F. R. A. Prado, Erick Archer, Arnd Bergmann, Anastasia
   Belova).

 - Update cpufreq-dt-platdev to block/approve devices (Richard Acayan).
