Zhao Liu 0d2d00e57a hw/core/machine: Reject thread level cache 
Currently, neither i386 nor ARM have real hardware support for per-
thread cache, and there is no clear demand for this specific cache
topology.

Additionally, since ARM even can't support this special cache topology
in device tree, it is unnecessary to support it at this moment, even
though per-thread cache might have potential scheduling benefits for
VMs without CPU affinity.

Therefore, disable thread-level cache topology in the general machine
part. At present, i386 has not enabled SMP cache, so disabling the
thread parameter does not pose compatibility issues.

In the future, if there is a clear demand for this feature, the correct
approach would be to add a new control field in MachineClass.smp_props
and enable it only for the machines that require it.
