Subject: [PATCH v2 4/5] ARM: dts: Add thermistor dts fragment used by exynos based Peach boards

From: Naveen Krishna Chatradhi <ch.naveen@...sung.com>

This patch creates a thermistor fragment carrying the NTC Thermistor
nodes as children of the IIO based ADC.

This fragment is included in exynos5420-peach-pit.dts and
exynos5800-peach-pi.dts.
