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.
