Add more fields and error flags to struct batt_params
This adds two battery parameters that need to be monitored constantly: remaining_capacity and full_capacity (that one only changes occasionally, but we have to notify the AP when it does). It also adds the is_present field to indicate whether the battery is physically present or not (when we can tell), so we know whether to try to wake up a deep-discharged battery. Along with that, we clean up the error flags to provide indication of which fields were unable to be read, and replace the manual logical-or of all errors as they were set with a bitmask (BATT_FLAG_BAD_ANY). No functionality is changed, only new & better information is provided for use in the upcoming cleanup of the charge state machine. BUG=chrome-os-partner:20881 BRANCH=ToT TEST=make buildall -j All targets build; all tests pass.
