drm/bridge: Patch atomic hooks to take a drm_bridge_state

This way the drm_bridge_funcs interface is consistent with the rest of
the subsystem.

The drivers implementing those hooks are patched too.

v10:
* Add changelog to the commit message

v8 -> v9:
* No changes

v7:
* Adjust things to the bridge_state changes

v6:
* Also fixed rcar-du/rcar_lvds.c same as analogix/analogix_dp_core.c

v5:
* No changes

v4:
* Rename func params into old_bridge_state
* Add Laurent's Rb

v3:
* Old state clarification moved to a separate patch

v2:
* Pass the old bridge state
