thermal: exynos: simplify temp_to_code() and code_to_temp()
* Remove dead temp check from temp_to_code() (this function users
in exynos_tmu_initialize() always pass correct temperatures and
exynos_tmu_set_emulation() returns early for EXYNOS4210 because
TMU_SUPPORT_EMULATION flag is not set on this SoC).
* Move temp_code check from code_to_temp() to exynos_tmu_read()
(code_to_temp() only user).
There should be no functional changes caused by this patch.
