[RFC 42/52] hw/machine: Add hybrid_supported in generic topo properties

[Zhao Liu]

From: Zhao Liu <zhao1....@intel.com>

Since hybrid cpu topology configuration can benefit not only x86, but
also other architectures/platforms that have supported (in real
machines) or will support hybrid CPU topology, "-hybrid" can be generic.

So add the generic topology property to configure if support hybrid
cpu topology for architectures/platforms in SmpCompatProps.

Also rename SmpCompatProps to TopoCompatProps to make this structure
more generic for both smp topology and hybrid topology.
