Works simliar to machine types, by adding a deprecation_reason field
(using the same name for easy grepping).  Also deprecate two devices:
adlib and cirrus.

This is tagged as RfC because the deprecation notice is not added to
introspecction yet.

Gerd Hoffmann (3):
  qdev: add deprecation_reason to DeviceClass
  adlib: mark as insecure and deprecated.
  cirrus: mark as deprecated
