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.
