iio: exynos_adc: use indio_dev->dev structure to handle child nodes
Using pdev->dev with device_for_each_child() would iterate over all
of the children of the platform device and delete them.
Thus, causing crashes during module unload.
We should be using the indio_dev->dev structure for
registering/unregistering child nodes.
