The ADC in S3C/S5P/Exynos SoCs can be used also for handling touch
screen. In such case the second interrupt is required. This second
interrupt can be anyway provided, even without touch screens. This
fixes dtbs_check warnings like:
arch/arm/boot/dts/s5pv210-aquila.dt.yaml: adc@e1700000: interrupts: [[23], [24]] is too long

Changes since v1:
1. Fix if:has-touchscreen, as pointed by Rob.
2. Add Ack.

The ADC in S5Pv210 does not have ADC phy registers in separate block for
which syscon would be needed. Remove this requirement to fix dtbs_check
warnings like:

Jonathan,
Could you pick up these two?
Best regards,

Done. Applied to the togreg branch of iio.git and pushed out
as testing for the autobuilders to possibly poke them.
Thanks,
