hw/i386/sev: Use legacy SEV VM types for older machine types
Newer 9.1 machine types will default to using the KVM_SEV_INIT2 API for
creating SEV/SEV-ES going forward. However, this API results in guest
measurement changes which are generally not expected for users of these
older guest types and can cause disruption if they switch to a newer
QEMU/kernel version. Avoid this by continuing to use the older
KVM_SEV_INIT/KVM_SEV_ES_INIT APIs for older machine types.
