ARM: h1940: Use gpiolib for latch access
This patch adds gpiolib support for h1940 latch. With this patch it's possible to use leds-gpio and uda1380 drivers (they require gpiolib support for appropriate pins). And now it's possible to drop leds-h1940 driver. Signed-off-by: Vasily Khoruzhick <anarsoul@gmail.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
