All DRM bridges are now supposed to be allocated using
devm_drm_bridge_alloc(), which is cleaner and necessary to support
refcounting.
Deprecate old school allocation using kzalloc and derivatives. In the
absence of a drm_bridge_init() or such initialization function, document
the deprecation on the first DRM bridge core function that is called after
allocation, i.e. drm_bridge_add().
