[PATCH v3 11/35] drm/bridge/analogix: Use drm_bridge_init()

[Mihail Atanassov]

No functional change.

The setting of bridge->of_node by drm_bridge_init() in
analogix_dp_core.c is safe, since ->of_node isn't used directly and the
bridge isn't published with drm_bridge_add().

v3:
 - drop driver_private argument (Laurent)
 - pass correct struct device pointer to drm_bridge_init (Laurent)
