[PATCH 2/8] PM: core: Add NS varients of EXPORT[_GPL]_SIMPLE_DEV_PM_OPS and runtime pm equiv

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

As more drivers start to use namespaces, we need to have varients of these
useful macros that allow the export to be in a particular namespace.
