Yes, it was tricky to me to decide the splits suggested by Daniel and
this is the example. I had to introduce the em_dev_register_perf_domain
and make clients of it before I remove the old em_register_perf_domain
completely. I agree it could also go with the patch 5, but it does not
harm to be here.

Thank you for this ACKs and the earlier.
