[PATCH 11/24] PM / Domains: Remove legacy API for adding devices through DT

[Ulf Hansson <ulf.hansson@linaro.org>]

There are no active clients of the legacy API and we now also have a
sophisticated way, where driver core deals with adding devices to genpd
while probing. So, let's remove the legacy API.
