The some device are not connected for ADC line on artik5-eval board.
This dt node just initialize the basic setting (clock,regulator) ADC of exynos3250 SoC.
(I'll change the board name from artik5-devel to artik5-eval on v2 patchset)
The vdd-supply for ADC is already fixed on artik5 module.

Okay. I'll merge it with 5/10 patch.
