iio:imu:kmx61: Switch from CONFIG_PM* guards to pm_ptr() etc 



Letting the compiler remove these functions when the kernel is built
without one or  more of CONFIG_PM/CONFIG_PM_SLEEP support is simpler and
less error prone than the use of #ifdef based config guards.

Removing instances of this approach from IIO also stops them being
copied into new drivers.
