Peter Maydell 7ea7b9ad53 qom/cpu: Add cluster_index to CPUState
For TCG we want to distinguish which cluster a CPU is in, and
we need to do it quickly. Cache the cluster index in the CPUState
struct, by having the cluster object set cpu->cluster_index for
each CPU child when it is realized.

This means that board/SoC code must add all CPUs to the cluster
before realizing the cluster object. Regrettably QOM provides no
way to prevent adding children to a realized object and no way for
the parent to be notified when a new child is added to it, so
we don't have any way to enforce/assert this constraint; all
we can do is document it in a comment. We can at least put in a
check that the cluster contains at least one CPU, which should
catch the typical cases of "realized cluster too early" or
"forgot to parent the CPUs into it".

The restriction on how many clusters can exist in the system
is imposed by TCG code which will be added in a subsequent commit,
but the check to enforce it in cluster.c fits better in this one.
