mb/google/dedede: Update CPU critical temperature
Observed thermal shutdown initiated by DPTF due to CPU temperature reaching critical temperature trip value. During stress testing with heavy workload like WebGL Aquarium, sometime CPU temperature spikes till 99 degree Celsius and DPTF initiates system shutdown. This updates CPU critical temperature trip value to 105 degree Celsius to avoid system shutdown.
