s390x: Remove deprecated machine types up to v4.0

[PATCH v2 4/9] target/s390x: Rename the qemu_V2_11 feature set to qemu_MIN

Posted by Thomas Huth 7 months, 2 weeks ago

From: Thomas Huth <thuth@redhat.com>

Now that the v2.11 machine type has been removed, it does not make
sense to keep the qemu_V2_11 feature set around. This is rather
the (minimum) feature set of the oldest supported machine now, so
rename it to qemu_MIN.
