This patch migrates the TMU register definition/bitfields to data file. This
is needed to support SoC's which use the same TMU controller but register
validity, offsets or bitfield may slightly vary across SOC's.

You changed from EXYNOS_TMU_TRIM_TEMP_MASK to EXYNOS_TMU_TEMP_MASK. Was
it this really what you wanted?

Is 4 your addressing unit? I believe there is a macro definition for this.
