[PATCH 6/6] iio: light: st_uvis25: Use EXPORT_NS_SIMPLE_DEV_PM_OPS()

[Jonathan Cameron <jic23@kernel.org>]

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

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.
