guybrush: Add fan thresholds to CPU temp sensor
If the SOC temp sensor fails for any reason, the CPU temp sensor should
be used as a backup to trigger the fan. Mostly guessing on thresholds
here. These values should be adjusted during thremal tuning.
BUG=b:190831599
TEST=Disable SOC sensor, see fan trigger when CPU temp reached 60
BRANCH=None
