thermal: exynos: remove TMU_SUPPORT_ADDRESS_MULTIPLE flag

Replace TMU_SUPPORT_ADDRESS_MULTIPLE flag check in exynos_map_dt_data()
by an explicit check for a SoC type (only Exynos5420 with TRIMINFO
quirk and Exynos5440 have TMU_SUPPORT_ADDRESS_MULTIPLE flag set in
their struct exynos_tmu_init_data instances).

Please note that this requires moving SoC type assignment and verification
from exynos_tmu_probe() to exynos_map_dt_data() so it happens earlier
(which is a good thing in itself).

There should be no functional changes caused by this patch.
