thermal: exynos: add ->tmu_control method

Add ->tmu_control method to struct exynos_tmu_data and use it
in exynos_tmu_control().  Then add ->tmu_control implementations
for Exynos4210+ and Exynos5440.  Finally remove no longer needed
reg->tmu_[ctrl,inten], reg->inten_rise[0,1,2,3]_shift and
reg->inten_fall0_shift abstractions.

There should be no functional changes caused by this patch.
