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.
