Why do you need this header file?

Given that you don't pass an id and your device-tree binding is that for
Cortex A15, I assume this patch series is based on my perf/updates branch?
That's good because it reduces the potential for conflicts, but you should
make sure that whoever you send this to is aware of the dependency.
