mb/google/brox/var/brox: update thermal settings to start fan early

Browse Source 
Current existing temperature thresholds of TSR1 sensor are set at 60C
to start fan. Due to this CPU gets hot and temperature goes over 80C.
In this situation, fan does not even start to lower down CPU temperature.

With updated new settings based on tuning from thermal team, start fan
early at 40C for TSR0 and TSR1 so the CPU temperature stays below 80C.

BUG=b:339493551
TEST=Built and tested on google/brox board
