Letting the compiler remove these functions when the kernel is built
without CONFIG_PM 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.

If CONFIG_PM_SLEEP is not defined using EXPORT_SIMPLE_DEV_PM_OPS()
in conjunction with pm_sleep_ptr() allows the compiler to remove
the unused code and data. This removes the need for __maybe_unused
markings etc.

Avoid unnecessary pollution of the global symbol namespace by
moving library functions in to a specific namespace and import
that into the drivers that make use of the functions.

These new functions move the burden of removing unused code when
CONFIG_PM_SLEEP is not defined onto the compiler rather than requiring
the use of CONFIG_PM guards and similar.

Avoid unnecessary pollution of the global symbol namespace by
moving library functions in to a specific namespace and import
that into the drivers that make use of the functions.
