From: Andy Yan <andy.yan@rock-chips.com> 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.
