drm/bridge: adapt drm_bridge_add/remove() docs, mention the lingering list

Browse Source 
The role of drm_bridge_add/remove() is more complex now after having added
the lingering list. Update the kdoc accordingly.

Also stop mentioning the global list(s) in the first line of the docs: the
most important thing to mention here is that bridges are registered and
deregistered, lists are just the type of container used to implement such
(de)registration.
