iio: imx8qxp-adc: mark PM functions as __maybe_unused
Without CONFIG_PM_SLEEP, the runtime suspend/resume functions are unused, producing a warning: drivers/iio/adc/imx8qxp-adc.c:433:12: error: 'imx8qxp_adc_runtime_resume' defined but not used [-Werror=unused-function] 433 | static int imx8qxp_adc_runtime_resume(struct device *dev) | ^~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/iio/adc/imx8qxp-adc.c:419:12: error: 'imx8qxp_adc_runtime_suspend' defined but not used [-Werror=unused-function] 419 | static int imx8qxp_adc_runtime_suspend(struct device *dev) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ Mark them as __maybe_unused to shut up the compiler.
