O-Subject: [RHEL8 qemu-kvm PATCH v2] Declare cirrus-vga as deprecated
Bugzilla: 1651994

BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1651994
Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=19300792
Upstream: n/a (downstream only)
Branch: rhel8/master-2.12.0
Branch: rhel8/master-3.0.0

The "cirrus" device in qemu-kvm is considered as a legacy device, which
also had a lot of security issues in the past. KVM guest should preferably
use "stdvga", "virtio-vga" or "qxl" as graphics card nowadays instead.
To avoid that we have to carry along the legacy "cirrus" device in
downstream qemu-kvm forever, let's mark it as deprecated in RHEL8 now,
so that we can finally remove it in RHEL9.
