[PATCH] docs/about: Change notes on x86 machine type deprecation into a general one

[Thomas Huth <thuth@redhat.com>]

We now have a general note about versioned machine types getting
deprecated and removed at the beginning of the deprecated.rst file,
so we should also have a general note about this in removed-features.rst
(which will also apply to versioned non-x86 machine types) instead of
listing individual old machine types in the document.
