drm/rockchip: use for_each_endpoint_of_node macro, drop endpoint reference on break
Using the for_each_... macro should make the code a bit shorter and easier to read. Also, when breaking out of the loop, the endpoint node reference count needs to be decremented. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Reviewed-by: Daniel Kurtz <djkurtz@chromium.org>
