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.
