This patch adds the TMU (Thermal Management Unit) sensor devicetree node for
Exynos5433. The Exynos5433 includes the five temperature sensors as following:
- two temperature sensor for Cortex-A57 (ATLAS)
- one temperature sensor for Cortex-A53 (APOLLO)
- one temperature sensor for G3D IP
- one temperature sensor for ISP IP
