drm/rcar-du: Plug atomic state hooks to the default implementation

This is needed to pass a bridge state to all atomic hooks, if we don't
do that, the core can't duplicate/create bridge states.

v10:
* Add changelog to the commit message

v9:
* Add Neil's R-b
* Move earlier in the series

v8:
* No changes

* New patch
