thermal: exynos: Adapt to temperature emulation core thermal framework
This removes the driver specific sysfs support of the temperature emulation and uses the newly added core thermal framework for thermal emulation. An exynos platform specific handler is added to support this. In this patch, the exynos senor(tmu) related code and exynos framework related (thermal zone, cooling devices) code are intentionally kept separate. So an emulated function pointer is passed from sensor to framework. This is beneficial in adding more sensor support using the same framework code which is an ongoing work. The goal is to finally split them totally. Even the existing read_temperature also follows the same execution method.
