veyron: fixed SUSPEND_L line
Pulled down line so it's not so erratic.
Fixes the issue where the EC doesn't know what state the AP is in.
BUG=None
TEST=EC should report S0 correctly(not S3 all the time). `power on` and
`power off` will also work correctly(instead of doing absolutelly nothing).
BRANCH=None
