For ec thermal control: [code_url](https://source.chromium.org/chromiumos/chromiumos/codesearch/+/main:src/plat...)
EC will read the temperature once per second to judge the current thermal state, and send corresponding events to the AP host via SCI “EC_HOST_EVENT_THERMAL_THRESHOLD = 9”  while it triggers the threshold.
