drm/atomic: Add dev pointer to drm_private_obj

All the objects that need to implement some callbacks in KMS have a
pointer in there structure to the main drm_device.

However, it's not the case for drm_private_objs, which makes it harder
than it needs to be to implement some of its callbacks. Let's add that
pointer.
