DTS files exynos5420-peach-pit.dts and exynos5800-peach-pi.dts have lots of device tree nodes in common. This patch creates a cros-exynos-peach.dts file, which can carry the device tree nodes common across exynos5420-peach-pit.dts and exynos5800-peach-pi.dts. Starting with ADC based Thermistor nodes. Also, enables ADC based thermistors for peach_pi and peach_pit.
