rambi: Fix driving keyboard column 2
Rambi's Silego chip inverts the pull as well as the signal. So it has
a pulldown for the signal instead of a pullup. The EC must drive the
signal push-pull, since open-drain only works for signals with pullups.
BUG=chrome-os-partner:23198
BRANCH=none
TEST=type on keyboard; C/D/E/3/F1-F4 should all work
