Marc Zyngier 31283877e3 KVM: arm64: Prevent mixed-width VM creation 
commit 66e94d5caf upstream.

It looks like we have tolerated creating mixed-width VMs since...
forever. However, that was never the intention, and we'd rather
not have to support that pointless complexity.

Forbid such a setup by making sure all the vcpus have the same
register width.
