[v2,2/3] iio: adc: at91-sama5d2_adc: remove predisable/postenable hooks

This should be squashed into the first patch, but it's the more peculiar of
the changes.
I am not sure whether this is correct. The touchscreen channels shouldn't
be enabled by the IIO framework. So, we may need a different way to handle
those if needed.
