On dual battery systems, this allows to keep both batteries
information in similar structures. This also means that battery
information can only be fetched via host commands
EC_CMD_BATTERY_GET_STATIC/DYNAMIC (next CL will make it possible
to fetch the information via shared memory/ACPI).
BRANCH=none
BUG=b:65697620
TEST=Boot lux/wand, dual-battery algorithm works, AP can fetch
both battery information via host commands.
