The intel_pin_to_gpio() function is only called by the PM support functions and causes a warning when those are disabled:
drivers/pinctrl/intel/pinctrl-intel.c:841:12: error: unused function 'intel_pin_to_gpio' [-Werror,-Wunused-function] As we cannot change the PM functions themselves to use __maybe_unused, add another #ifdef here for consistency.
