[PATCH 2/2] iio: temp: mlx90632: Switch form UNVIVERSAL to DEFINE_RUNTIME_DEV_PM_OPS()

[Jonathan Cameron <jic23@kernel.org>]

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

The callbacks in this driver are simple and it doesn't matter if
they are unnecessarily called multiple times.  However, we might as
well not repeat the effort if the device is already suspended.
The new DEFINE_RUNTIME_DEV_PM_OPS() has the advantage that we don't
need to mark the callbacks __maybe_unused.  The compiler will still
remove them for us if CONFIG_PM is not set.
