devlink: push object register/unregister notifications into separate helpers

Browse Source 
In preparations of leftover.c split to individual files, avoid need to
have object structures exposed in devl_internal.h and allow to have them
maintained in object files.

The register/unregister notifications need to know the structures
to iterate lists. To avoid the need, introduce per-object
register/unregister notification helpers and use them.
