Subject: [PATCH 08/10] ARM: dts: Add rtc and adc dt node for exynos3250-artik5
 module

This patch adds the RTC (Real Time Clock) and ADC (Analog Digital Converter)
Device Tree node for exynos3250-artik5 module. The RTC is used for wakeup
source and the ADC is used to read the analog data such as battery temperature.

ADC need to connect the some H/W device such as battery. So, this patch just
adds the default setting (clock, regulator).
