* 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.
