We are about to add a drm_bridge_state that inherits from drm_private_state which is defined in drm_atomic.h. Problem is, drm_atomic.h includes drm_crtc.h which in turn includes drm_bridge.h, leading to "drm_private_state has incomplete type" error. Let's force all users of the drm_bridge API to explicitly include drm_bridge.h.
