[RFC 12/52] hw/acpi: Replace MachineState.smp access with topology helpers

[Zhao Liu]

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

At present, in QEMU only arm needs PPTT table to build cpu topology.

Before QEMU's arm supports hybrid architectures, it's enough to limit
the cpu topology of PPTT to smp type through the explicit smp interface
(machine_topo_get_smp_threads()).
