dt-bindings: msm/dsi: Modify port and PHY bindings
The DSI node now has two ports that describe the connection between the MDP interface output and the DSI input, and the connection between the DSI output and the connected panel/bridge. Update the properties and the example. Also, use generic PHY bindings instead of the custom one.
