this is the first commit to make sure nothing gets lost.

+Subject: [PATCH 13/76] thermal: Use IS_ENABLED instead of #ifdef
+
+Use IS_ENABLED(CONFIG_THERMAL_EMULATION) to make the code more readable
+and to get rid of the addtional #ifdef around the variable definitions
+in thermal_zone_get_temp().
