iio:common:ssp: Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() etc

Browse Source 
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 switch to SIMPLE_DEV_PM_OPS
rather than open coding the structure.

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