x86: Factor out pc_new_cpu
At this point, this refactoring looks like overkill. But we will need it for CPU hotplugging, and qemu-kvm already carries it. Merging it early would help qemu-kvm when rebasing against upstream. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
