[PATCH 27/33] ARM: dts: exynos: Override thermal by label in Exynos4412 Odroids

Using full paths to extend or override a device tree node is error prone since if there was a typo error, a new node will be created instead of extending the node as it was desired. This will lead to run-time errors that could be hard to detect. A mistyped label on the other hand, will cause a dtc compile error (during build time).
