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)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~

419 | static int imx8qxp_adc_runtime_suspend(struct device *dev)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~
Mark them as __maybe_unused to shut up the compiler.

Looks the same as
https://lore.kernel.org/all/[email protected]/
but that one is mixing the Fixes: tag.

Given Cai replied to this one and the presence of the fixes tag + my inherent
laziness, applied this one to the togreg branch of iio.git. I'll push that
out as testing to let 0-day poke it before pushing it out for next to pick up
in a day or 2.
Thanks,
