Changes in v7:

• Set atomic state hooks explicitly

Changes in v3:

• Adjust things to match the new bus-format negotiation approach
• Use drm_atomic_helper_bridge_propagate_bus_fmt
• Don't implement ->atomic_check() (the core now takes care of bus flags propagation)

Changes in v2:

• Adjust things to match the new bus-format negotiation approach
