Revert "drm/bridge: ti-sn65dsi86: Implement bridge connector operations for DP"
As reported by Laurent in response to this commit[1], this functionality should not be implemented using the devicetree, because of this let's revert this series for now. This reverts commit c312b0df3b13e4c533743bb2c37fd1bc237368e5.
