Trip points corresponding to the one defined in the exynos_tmu_data.c
for Exynos5422 have been included so define thermal-zones attribute.

Changes rebase on git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung branch for-next
Changes from v5 : Rename exynos5-cpu-thermal.dtsi to exynos5422-cpu-thermal.dtsi
as this file belongs to exynos5422 boards
