Libvirt calls cpuArchDriver.compare() while doing guest migration.
We don't have any logic to distinguish between different arm and
aarch64 models that's why this patch allows migration to any host.

Openstack Nova calls virConnectBaselineCPU() during initialization
of the instance to get a full list of CPU features.
This patch adds a stub to aarch64-specific code to handle
this request (no actual work is done). That's enough to have
this stub with limited functionality because qemu/kvm backend
supports only 'host-passthrough' cpu mode on aarch64.

This patch allows libvirt user to specify 'host-passthrough'
cpu mode while using qemu/kvm backend on aarch64.
It uses 'host' as a CPU model name instead of some other stub
(correct CPU detection is not implemented yet) to allow libvirt
user to specify 'host-model' cpu mode as well.
