Subject: [PATCH 25/33] thermal: exynos: remove TMU_SUPPORT_FALLING_TRIP flag

Replace TMU_SUPPORT_FALLING_TRIP flag check in
exynos[4210,5440]_tmu_control() by an explicit check
for a SoC type (all SoC types except Exynos4210 have
TMU_SUPPORT_FALLING_TRIP flag set in their struct
exynos_tmu_init_data instances).

There should be no functional changes caused by this patch.
