From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

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.
