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.
