The QMP query displays a simple flag for deprecation, while '-cpu help' displays nothing unless the deprecation info is duplicated into the 'notes' field. This changes the code so that deprecation notes are explicitly shown in '-cpu help', to assist the user in deciding what to use. Signed-off-by: Daniel P.
