This data is used to populate the _BIF/_BIX packages in ACPI but it currently needs an EC command to retrieve that isn't easy to query in ACPI since it isn't using standard EC RAM. 1) Export these additional fields in init() state: - Design Capacity of Full - Design Voltage - Last Full Charge Capacity - Cycle Count - Manufacturer String - Model String - Serial Number String 2) Fix an issue where battery current was not reported when the battery was charging. 3) Remove the command interface so there is no duplication. BUG=chrome-os-partner:7734 TEST=using (not yet published) coreboot to read battery status via ACPI and verify that battery removal/insertion events are properly handled.

- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.

---- chip interface ---- The interface is defined in
src/platform/ec/chip_interface/*.
