Merge five ACPI driver updates for 6.15-rc1:

 - Use the str_on_off() helper function instead of hard-coded strings in
   the ACPI power resources handling code (Thorsten Blum).

 - Add fan speed reporting for ACPI fans that have _FST, but otherwise
   do not support the entire ACPI 4 fan interface (Joshua Grisham).

 - Fix a stale comment regarding trip points in acpi_thermal_add() that
   diverged from the commented code after removing _CRT evaluation from
   acpi_thermal_get_trip_points() (xueqin Luo).

 - Make ACPI button driver also subscribe to system events (Mario
   Limonciello).

 - Use the str_yes_no() helper function instead of hard-coded strings in
   the ACPI backlight (video) driver (Thorsten Blum).
