500d91311f hypervisor: aarch64: kvm: use concrete KvmVm type where possible 
The code was moved from the vmm crate to the hypervisor crate. After the
move it is trivially obvious that it only works with KVM. Use concrete
types where possible.

This allows us to drop create_device from the Vm trait.

No functional change intended.

For the moment we cannot provide a default variant for the new type,
because picking one will be wrong for the other hypervisor, so I just
