Falco: Stop charging after a timeout of 10 hours
BUG=chrome-os-partner:20145
BRANCH=falco
TEST=Hack it. Add (uint64_t)599 * MINUTE to ctx->curr.ts.val
in the timeout comparison. This makes the 10 hour timeout only
take 1 minute. Testing this directly is tricky as a healthy battery
will charge quickly. If you force it to trickle charge it will
give up before 10 hours pass.
