set CPUID bits to present cores and threads topology
Controlled by the enhanced -smp option set the CPUID bits to present the guest the desired topology. This is vendor specific, but (with the exception of the CMP_LEGACY bit) not conflicting, so we set all bits everytime. There is no real multithreading support for AMD CPUs, so report cores instead.
