hw/arm/smmuv3: Add knob to choose translation stage and enable stage-2
As everything is in place, we can use a new system property to advertise which stage is supported and remove bad_ste from STE stage2 config. The property added arm-smmuv3.stage can have 3 values: - "1": Stage-1 only is advertised. - "2": Stage-2 only is advertised. If not passed or an unsupported value is passed, it will default to stage-1. Advertise VMID16. Don't try to decode CD, if stage-2 is configured.
