I'm not sure I follow the motivation for having this under drivers/soc?

In fact, my (possibly incorrect) understanding of this Resource Power
Manager is that it's actually to manage communication/control of
resources that are actually handled off the SoC by a microcontroller.

I added Paul W. to Cc so he can correct me, but I think this is a ways
off from the goal of what drivers/soc was for.
