thermal: exynos: add sanitize_temp_error() helper
Factor out code for initializing data->temp_error[1,2] values from exynos_tmu_initialize() into sanitize_temp_error(). This is a preparation for introducing per-SoC type tmu_initialize method. There should be no functional changes caused by this patch.
