drm/bridge: analogix_dp: Add &analogix_dp_plat_data.next_bridge

In order to move the panel/bridge parsing and attachmenet to the
Analogix side, add component struct drm_bridge *next_bridge to
platform data struct analogix_dp_plat_data.

The movement makes sense because the panel/bridge should logically
be positioned behind the Analogix bridge in the display pipeline.
