It is done, because when the driver's ->resume() or ->restore() brings the
device up (which should have happened if it returned 0), we need to mark
the device as "active" for runtime PM.

Since __pm_generic_resume() does that, it's not necessary to do it in the
bus type callbacks (in the "legacy" case we known that runtime PM is not
supported).

Thanks,
Rafael
