kvm: arm64: Switch to per VM IPA limit
Now that we can manage the stage2 page table per VM, switch the configuration details to per VM instance. The VTCR is updated with the values specific to the VM based on the configuration. We store the IPA size and the number of stage2 page table levels for the guest already in VTCR. Decode it back from the vtcr field wherever we need it.
