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.
In this case SIMPLE_DEV_PM_OPS() could have been used previously.
Now we have DEFINE_SIMPLE_DEV_PM_OPS() which also deals with letting
the compiler remove the structure and functions so use that instead.
