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

[Chanwoo Choi]

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
