Subject: [PATCH 23/33] 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.
