[PATCH v3 4/9] drivercore / platform: Convert to dev_pm_domain_attach|detach()

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

Previously only the ACPI PM domain was supported by the platform bus.

Let's convert to the common attach/detach functions for PM domains,
which currently means we are extending the support to include the
generic PM domain as well.
