How about moving it to drivers/power/domain/ instead? We already
have some only loosely connected subsystems under drivers/power
today (reset and supply, both maintained by Sebastian Reichel),
moving it there is probably less confusing.

It looks like there are only a couple of dev_pm_domain providers
that are not of the "genpd" variant, so I think drivers/power/domain
can just be the location for the generic drivers without making
that part of the name.

I don't think we can easily rename the interfaces that have been
in use for the past 12 years, but the directory (and MAINTAINERS
file references to it) could easily be changed with another
patch on top of Ulf's series, without interfering with my
pull requests.
