There is no longer need to share defines between exynos_tmu.c and exynos_tmu_data.c (as they are now only used by the former file) so move them accordingly. Then move externs for struct exynos_tmu_init_data instances to exynos_tmu.h and remove no longer needed exynos_tmu_data.h include. There should be no functional changes caused by this patch.
