Adding in basic menu support (using arrow keys) for detachables, which do not have keyboards. Thus, we can only do menu scrolling rather than the old ctrl+D/U/L way. This is specifically for the developer warning menu. BUG=chrome-os-partner:61275 BRANCH=None TEST=reboot system and try scrolling through menu Change-Id: I39f56f5ca2fedd47df53ab246ec357d07c9c4af0 Signed-off-by: Shelley Chen <shchen@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/424353 Reviewed-by: Randall Spangler <rspangler@chromium.org>
