This is wrong, and must go. There should be a separate node for the PMU
of each microarchitecture, with the appropriate compatible string to
represent that (see the juno dts).

In this case things are messier as the same PPI number is being used
across clusters. Marc (Cc'd) has been working on PPI partitions, which
should allow us to support that.

Thanks,
Mark.
