[PATCH 1/5] ARM: dts: exynos4x12: Add ADC's dt data to read raw data

This patch add ADC(Analog to Digital Converter)'s dt data to get raw data
with IIO subsystem. Usually, ADC is used to check temperature, jack type, and
so on.

Register map
- <0x126C0000 0x100> : ADC register's base address
- <0x10020718 0x4> : ADC_PHY_CONTROL, TS-ADC control register address

Clock
- <&clock 326> : ADC clock (clock name :'tsadc')

Interrupt
- INTG10[3] : ADC for General ADC
