ec_ec_comm_slave: Define extpower_is_present
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.
