[PATCH v7 8/9] arm64: dts: rockchip: Add missing dp_out port for RK3399 CDN-DP

[Chaoyi Chen <kernel@airkyi.com>]

From: Chaoyi Chen <chaoyi.chen@rock-chips.com>

Let's make the ports nodes of cdn_dp in the same style as the other
display interface, and match the style of ports's yaml.

Signed-off-by: Chaoyi Chen <chaoyi.chen@rock-chips.com>
