thermal: exynos: Add missing definations and code cleanup
This patch adds some extra register bitfield definations and cleans up the code to prepare for moving register macros and definations inside the TMU data section. In this code cleanup the TMU enable bit is correctly used as bit0 and bit1 is taken care which is reserve bit.
