Fixes for Samsung DTS ARM for v6.3

Browse source 
Thermal framework commit 3fd6d6e2b4 ("thermal/of: Rework the thermal
 device tree initialization") merged in v6.1-rc1, exposed
 misconfiguration of Exynos Thermal Monitoring Unit (TMU) thermal-sensors
 property in DTS.  This misconfiguration in DTS was working fine before
 that Thermal commit, but now all thermal zones fail to register except
 the first one (CPU).  This can lead to missing cooling of a board and
 eventually either emergency shutdown or damaged board.
