Running an Antutu benchmark makes the board to do a hard reboot. Cause: it appears the gpu-bottom and gpu-top temperature sensors are showing too high temperatures, above 115°C. Out of tree configuratons show the gpu thermal zone is configured to be mitigated at 85°C with devfreq. Add the DT snippet to enable the thermal mitigation on the sdm845 based board.
