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.
