thermal: exynos: add ->tmu_set_emulation method 

Add ->tmu_set_emulation method to struct exynos_tmu_data and
use it in exynos_tmu_set_emulation().  Then add ->tmu_set_emulation
implementations for Exynos4412+ and Exynos5440.  Finally remove
no longer needed reg->emul_con abstraction.

There should be no functional changes caused by this patch.
