iio:magn:mmc35240: Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() etc
Letting the compiler remove these functions when the kernel is built without CONFIG_PM_SLEEP support is simpler and less error prone than the use of #ifdef based config guards. Also use SIMPLE_DEV_PM_OPS instead of open-coding the equivalent. Removing instances of this approach from IIO also stops them being copied into new drivers.
