Subject: [PATCH 1/2] thermal: exynos: Add the dependency of CONFIG_THERMAL_OF
 instead of CONFIG_OF

The exynos thermal driver use the of_thermal_*() API to parse the basic data
for thermal management from devicetree file. So, if CONFIG_EXYNOS_THERMAL is
selected without CONFIG_THERMAL_OF, kernel can build it without any problem.
But, exynos thermal driver is not working with following error log. This patch
add the dependency of CONFIG_THERMAL_OF instead of CONFIG_OF.

[    1.458644] get_th_reg: Cannot get trip points from of-thermal.c!
[    1.459096] get_th_reg: Cannot get trip points from of-thermal.c!
[    1.465211] exynos4412_tmu_initialize: No CRITICAL trip point defined at of-thermal.c!
