Mostafa Saleh 8cefcc3b71 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.
