thermal: exynos: remove parsing of samsung, tmu_reference_voltage property

Since pdata reference_voltage values are SoC (not platform) specific
just move it from platform data to struct exynos_tmu_data instance.
Then remove parsing of samsung,tmu_reference_voltage property.

There should be no functional changes caused by this patch.
