platform/chrome: Update binary interface for EC-based charge control

Browse Source 
The charge-control command v2/v3 is more featureful than v1, it
additionally supports charge thresholds.

The definitions were imported from ChromeOS EC commit
32870d602317 ("squirtle: modify motionsense rotation matrix")
