Allows the lid to hibernate the base.
BRANCH=none
BUG=b:71874971
TEST=With following change, lid hibernates the base when in S5,
and no AC is connected.

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.

This function sets up and enables "OTG" mode on the charger chip
(i.e. use the charger to provide power from the battery).
It also records the output current in curr.output_current, to
make sure that the charger loop is aware that current is provided
externally.
We also add a CONFIG_CHARGER_OTG to remove these functions on
boards that do not require it.
BRANCH=none
BUG=b:65697962
TEST=On wand, when discharging, battery status is updated every
5 seconds (and not every 60 seconds).

Modify chipset_in_state to always say that the chipset is off,
when we do not actually have a chipset (like on hammer): that
makes sure the battery can actually be cut off (else the EC
would just wait forever for the chipset to turn off).
Also, wake the charger state on "AC" change, that is, when
charging_allowed changes state, to make sure the charging loop
is executed after lux tries to charge it (else the charging loop
would wait until timeout expires, and wand would ask the battery
to be cut off again).
BRANCH=none
BUG=b:65697962
TEST=Deplete wand battery, reboot without providing external power
to it.
After 30 seconds, battery is cut off:
[1.354683 Low battery: 2%, 6866mV]
[1.354888 charge warn shutdown due to critical battery]
[31.381410 Low battery: 2%, 6865mV]
[31.381643 charge force battery cut-off due to critical level]
TEST=Upon providing power to wand, charging loop is executed
regularly, and battery is charging.

On dual-battery slave, we use the charging allowed signal from
master to indicate whether external power is present.
In most cases, this actually matches the external power status
of the master (slave battery charging when AC is connected, or
discharging when slave battery still has enough capacity), with
one exception: when we do master to slave battery charging (in
this case the "external" power is the master).
BRANCH=none
BUG=b:65697962
TEST=Deplete wand battery to 5%, see that lux still provides power
to it but the battery does not charge.

This adds functions required for the slave in EC-EC communication,
including the task that processes requests from the master.
This also adds required CONFIG_EC_EC_COMM_SLAVE/MASTER/BATTERY
config options.
BRANCH=none
BUG=b:65697962
TEST=Build wand and lux boards, flash it, EC-EC communication works.
