 to v6.2

RH-Author: Thomas Huth <thuth@redhat.com>
RH-MergeRequest: 80: Add s390x machine type compatibility handling for the rebase to v6.2
RH-Commit: [26/26] c45cf594604f6dd23954696b9c84d2025e328d11
RH-Bugzilla: 2022602

Add compatibility handling for the rhel8.5.0 machine type (and
recursively older, of course).

Based on the following upstream commits:

 463e50da8b - s390x/cpumodel: Bump up QEMU model to a stripped-down IBM z14 GA2
 30e398f796 - s390x/cpumodel: Add more feature to gen16 default model
 4a0af2930a - machine: Prefer cores over sockets in smp parsing since 6.2
 2b52619994 - machine: Move smp_prefer_sockets to struct SMPCompatProps
