Ensure CEC bus pin is not driven low
We have seen cases where after a cold EC reboot the pin is low until the
first CEC message is sent by AP (after which the bus is left in a well
defined state again)
This is a follow up to https://crrev.com/c/1346990 which initializes
the pull up in case not done by the RO FW.
BRANCH=none
BUG=b:144548408
TEST=CEC pin only goes low for ~40ms instead of 30s.
