[PATCH 5/5] iio: adc: cc10001: Switch remaining IIO calls in probe to devm_ forms.

[Jonathan Cameron <jic23@kernel.org>]

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

As everything else is now handled by devm managed releases the
triggered buffer setup and IIO device registration can also be
moved over to their devm forms allowing dropping of remove().
