Switching to these newer macros allows the compiler to remove
the unused functions and struct dev_pm_ops if !CONFIG_PM without
the need to mark anything __maybe_unused.

Do not trust the fact that iio.h includes of.h which in turn includes
all the headers we are relying on.
The ultimate goal is to actually drop of.h from iio.h.

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.

The NXP i.MX 8QuadXPlus SOC has a new ADC IP, so add
driver support for this ADC.
