Luca Ceresoli 9347f2fbb0 drm/bridge: add warning for bridges using neither devm_drm_bridge_alloc() nor drm_bridge_add() 
The correct sequence for bridge initialization is:

 1. devm_drm_bridge_alloc()
 2. drm_bridge_add()
 3. drm_bridge_attach()

For bridges missing either 1 or 2 there are warnings in place already,
presenting an explanatory error message.

Bridges missing both 1 and 2 would still face a poorly understandable
message, as reported in a recent regression report [0]:

  WARNING: [...] at [...]/lib/refcount.c:25 drm_bridge_attach+0x2c/0x1dc
  ...
  Call trace:
  ...
   drm_bridge_attach
  ...

Add a new warning to ensure an understandable message is logged in such
cases. Use the same message and warning message already in place in
drm_bridge_add().
