zephyr: Add support for discharge testing
Add support for CHARGER_DISCHARGE_ON_AC and a choice for which method
to use to implement it. This does not seem to be all that common, so
leave it to default to off.
Drop the existing hard-coded setting. This option is often implemented
by the charger but the board should still select whether to use it or
not as there may be multiple chargers.
Enable it for volteer to keep things the same there.
BUG=b:183296099, b:175881762
BRANCH=none
TEST=with other CLs, build zephyr for lazor and see that the option is
present
check volteer still has the option enabled
