thermal: exynos: remove parsing of samsung, tmu[_min, _max]_efuse_value properties 

Since pdata efuse values are SoC (not platform) specific just move
them from platform data to struct exynos_tmu_data instance. Then
remove parsing of samsung,tmu[_,min_,max]_efuse_value properties.

There should be no functional changes caused by this patch.
