Original change's description:
> hana: disable console input when system is locked
>
> Shipped devices were found that batteries could enter ship mode
> unexpectedly. Fail rate is about 5/700pcs per day. Failure happens
> when battery is charged fully and eneters sleep(mem), and then AC is
> plugged out.
> Battery ship mode is entered because ec execute console command
> "cutoff". Still do not know what causes that when no any device
> connected to servo board connector (console TX and RX are floated).
> Enable this config item will cut off route from RX input and fix
> the issue.
>
> BUG=b:67033247
> BRANCH=none
> TEST=with 50 DUTs, flash ec to DUTs and then lock the system, charge
> the battery from about 80% capacity to 100% capacity, close the lid
> for 20 minutes, unplug AC, boot the system, all DUTs boot, no DUT's
> battery enter ship mode. The same test repeats 3 times.
