To keep compatibility with 8.5-AV machine type we need to
turn few new options on by default:
smp_props.prefer_sockets, no_cpu_topology, no_tcg_its

TESTED: migrate from rhel-av-8.5.0 to rhel-8.6.0 and vice-versa
with upstream fix: 33a0c404fb  hw/intc/arm_gicv3_its: Revert version
increments in vmstate_its
