arm64: dts: rockchip: Enable DisplayPort for rk3588s Cool Pi 4B

Enable the Mini DisplayPort on this board.
Note that ROCKCHIP_VOP2_EP_DP0 is defined as 10 in dt-binding header,
but it will trigger a dtc warning like "graph node unit address error,
expected "a"" if we use it directly after endpoint, so we use "a"
instead here.
