Remove runtime checks for negative return values of temp_to_code()
from exynos_tmu_initialize(). The current level temperature data
hardcoded in pdata will never cause a negative temp_to_code()
return values and for the new code potential mistakes should be
caught during development/review phases.
Theres should be no functional changes caused by this patch.
