Introduce a 'first-cpu-index' property for specifying the first QEMU CPU
connected to the GICv3. This makes it possible to have multiple instances
of the GICv3 connected to different CPU clusters.
For KVM, mark this property has unsupported. It probably does not make
much sense as it is intented to be used to model non-SMP systems.

Could we have a description for this new field? (Can be done by another
patch on top).
