I checked a couple of callbacks and they seem to all be called with
priv->iomem as an arg, so there is no strong reason to pass iomem
instead of priv / hw. Or at least not to pass both..

I think that's a better approach than adding the wrappers :(

Are you familiar with coccinelle / spatch? It's often better than 
just regexps for refactoring, maybe it can help?
