thermal: exynos: add ->tmu_read method

Add ->tmu_read method to struct exynos_tmu_data and use it
in exynos_tmu_control().  Then add ->tmu_read implementations
for Exynos4210, Exynos4412+ and Exynos5440.  Finally remove
no longer needed reg->tmu_cur_temp abstractions.

There should be no functional changes caused by this patch.
