PS4, Line 433: google_chromeec_is_battery_present
> Yes - Thanks I will create a separate patch . […]

i'm not convinced about using
`google_chromeec_is_battery_present`
vs.
`google_chromeec_is_battery_present_and_above_critical_threshold`
but i'm OK with adding the API and deferring the discussion
about which to use to specific use cases.
