This value matches what is used by the downstream Chrome OS 3.14
kernel, the 'official' kernel for veyron devices. Keep the temperature
for 'speedy' at 90°C, as in the downstream kernel.
Increase the temperature for a hardware shutdown to 125°C, which
matches the downstream configuration and gives the system a chance
to shut down orderly at the criticial trip point.
