[PATCH 1/3] thermal: st: switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr()

[Raphael Gallais-Pou]

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 kernel configuration guards.

Remove those guards on every ST thermal related drivers.
