This sets the EC_INT GPIO as an open-drain output and initializes it in high-impedence state. Signed-off-by: David Hendricks <dhendrix@chromium.org> BUG=none TEST=tested on daisy (applied keyboard patch and tested that AP gets interrupted and requests keyboard state upon keypress) Change-Id: Id4b043dd0066db823cd1502bd738f69bb656eada
