drm/bridge: analogix_dp: don't create a panel_bridge

Now a panel_bridge is automatically created for every drm_panel and the
panel-bridge API is just a deprecated wrapper to access it.

Update and simplify the code by just getting a reference to the
already-existing bridge using of_drm_get_bridge_by_endpoint().

As of_drm_get_bridge_by_endpoint() returns a refcounted bridge, take care
of putting the bridge reference. This is not easily done in the remove path
due to the different probe paths of the user drivers, so add a devm action
to ensure the reference is put only when it was taken.
