iio: exynos-adc: request second interupt only when touchscreen mode is used 

commit 865b080e32 upstream.

Second interrupt is needed only when touchscreen mode is used, so don't
request it unconditionally. This removes the following annoying warning
during boot:

exynos-adc 14d10000.adc: error -ENXIO: IRQ index 1 not found
