[PATCH 3/3] target/arm: display deprecation note in '-cpu help'

["Daniel P. Berrangé" <berrange@redhat.com>]

The deprecation notes are currently only displayed at runtime when the
user activates a CPU. 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.
