mb/google/rex/var/rex0: update thermal settings to start fan earlier
Internal testing showed that CPU heatsink gets hot and temperature
goes over 75C. In this situation, the fan does not even start
to lower down CPU temperature. This is because of existing temperature
thresholds of TSR0 and TSR1 sensors are set at 45C to start fan.
With updated new settings based on tuning from thermal team,
the fan starts early at 43C for TSR0 and TSR1 so the CPU temperature
stays below 75C.
