Merge branches 'pm-cpuidle' and 'pm-powercap'

Merge cpuidle and power capping changes for 6.18-rc1:

 - Fail cpuidle device registration if there is one already to avoid
   sysfs-related issues (Rafael Wysocki)

 - Use sysfs_emit()/sysfs_emit_at() instead of sprintf()/scnprintf() in
   cpuidle (Vivek Yadav)

 - Fix device and OF node leaks at probe in the qcom-spm cpuidle driver
   and drop unnecessary initialisations from it (Johan Hovold)

 - Remove unnecessary address-of operators from the intel_idle cpuidle
   driver (Kaushlendra Kumar)

 - Rearrange main loop in menu_select() to make the code in that funtion
   easier to follow (Rafael Wysocki)

 - Convert values in microseconds to ktime using us_to_ktime() where
   applicable in the intel_idle power capping driver (Xichao Zhao)
