api: export LCD device to external apps
This patch exports LCD info-query and bitmap-rendering functions to external apps. This patch is tested on a Seaboard. Because the LCD driver is not yet upstreamed, the test was done in a local downstream repo. Signed-off-by: Che-Liang Chiou <clchiou@chromium.org>
