drm/atomic-helper: Add private_obj atomic_create_state helper

Browse source

Now that we have an atomic_create_state callback for drm_private_objs,
we can provide a helper for it.

It's somewhat different from the other similar helpers though, because
we definitely expect drm_private_obj to be subclassed. It wouldn't make
sense for a driver to use it as-is.

So we can't provide a straight implementation of the atomic_create_state
callback, but rather we provide the parts that will deal with the
drm_private_obj initialization, and we will leave the allocation and
initialization of the subclass to drivers.
