thermal: exynos: remove threshold_code checking from exynos4210_tmu_initialize()

Browse source 
On Exynos4210 one-point trimming is always used and data->temp_error1
is equal to 75. Therefore temp_to_code() will never return negative
value for the reference temperature conversion.

There should be no functional changes caused by this patch.
