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.

The values match thorse used by the downstream Chrome OS 3.14
kernel, the 'official' kernel for veyron devices. Keep the critical
trip point for speedy at 90°C as in the downstream configuration.

Raise the temperature of the GPU thermal trip point for speedy
to 80°C. This is the value used by the downstream Chrome OS 3.14
kernel, the 'official' kernel for speedy.

applied all 3 for 5.3 with Doug's RB and did a small fix to the commit
message of patch2 ("thorse").
