iio: light: st_uvis25: Use EXPORT_NS_SIMPLE_DEV_PM_OPS()

Browse source 
Using this new macro removes the need to mark the callbacks
__maybe_unused.  One slightly complexity in this case is that
the export will exist if CONFIG_PM is set, but only be used
if CONFIG_PM_SLEEP is also set. This is harmless.
