ppc: add host-serial and host-model machine attributes (CVE-2019-8934)
On ppc hosts, hypervisor shares following system attributes - /proc/device-tree/system-id - /proc/device-tree/model with a guest. This could lead to information leakage and misuse.[*] Add machine attributes to control such system information exposure to a guest.
