From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>
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.
Removing instances of this approach from IIO also stops them being
copied into new drivers.
The pm_ptr() macro only removes the reference if CONFIG_PM is not
set. It is possible for CONFIG_PM=y without CONFIG_SLEEP, so this
will not always remove the pm_ops structure.
