Add new "port@1" property which represents the CDN DP output to keep the same style as the other display interfaces. This patch also changes the constraints for "phys" and "extcon". For the original binding, only one phy and the corresponding extcon can be specified. In the new binding, one or two phys can be specified. Since the RK3399 has two DP-USB PHYs, specifying one allows output via the corresponding PHY, while specifying two lets the driver choose one PHY for output. This rule also applies to extcon, which provides the cable state for the corresponding PHY.
