Following change removes the base_second field eliminates its mapping in exynos_map_dt_data(), and updates the TRIMINFO access logic in exynos4412_tmu_initialize() to use base for both Exynos5420 and Exynos5420_TRIMINFO SoCs, as base_second is not used further in in this code. This cleanup simplifies the code and reduces unnecessary memory mapping.
