[PATCH v4 10/15] iio: adc: ti-ads1015: Use device_for_each_child_node_scoped()

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

Switching to the _scoped() version removes the need for manual
calling of fwnode_handle_put() in the paths where the code
exits the loop early. In this case that's all in error paths.
