drm/bridge: tc358767: Move (e)DP bridge endpoint parsing into dedicated function
The TC358767/TC358867/TC9595 are all capable of operating in multiple modes, DPI-to-(e)DP, DSI-to-(e)DP, DSI-to-DPI. Only the first mode is currently supported. In order to support the rest of the modes without making the tc_probe() overly long, split the bridge endpoint parsing into dedicated function, where the necessary logic to detect the bridge mode based on which endpoints are connected, can be implemented.
