This patch adds the thermal-zones devicetree node for Exynos5433 SoC. The thermal-zones has five thermal-zones and then each thermal-zone contains each thermal-sensor to monitor the temperature of own IP. The {atlas0|apollo}_ thermal zone have the eight trip-points for interrupt method to detect the over-temperature.
