MIPS: MT: proc: Add support for printing VPE and TC ids
And there are more CPUs or configurations that want to provide special
per-CPU information in /proc/cpuinfo. So I think there needs to be a
hook mechanism, such as a notifier.
This is a first cut only; I need to think about what sort of looking
the notifier needs to have. But I'd appreciate testing on MT hardware!
