Thermal data incomplete

[aaron97neu]

For whatever reason our Grafana dashboard only shows data for some of the nodes. Toradex documentation found below shows that this data should be found in /sys/devices/virtual/thermal/thermal_zone0/temp. For some reason, this only shows up in some nodes.

Investigate why only some of the nodes have thermal data and if there is a software solution to get it on the rest of the nodes or if this is a hardware issue (different board revs?)
