Properties can't be attached after registering, userspace would get
confused (no one bothers to reprobe really).
- Add kerneldoc
- Enforce this with some checks. This needs a somewhat ugly check
since connectors can be added later on, but we still need to attach
all properties before they go public.
Note that we already enforce that properties themselves are created
before the entire device is registered.
Unfortunately this doesn't work for drivers which have a ->load
callback, see

drm/kms: Duct-tape for mode object lifetime checks
for the full story.
v2: Fix the superflous newline (Jani) and add commit citation to
explain why we need to check for dev->registered (Thierry).
