Looks like yes.

A little closer inspection makes me want to skip this. PM domains
can have multiple "master" domains, and pm_genpd_init() is the
only API that would be able to do the linking. That API is mostly
about initializing things to default values, so it doesn't seem
like a good fit. I'll send a v2 with the remove part and the
exports.
