So that the previous bridge element in the chain knows which input
format the panel bridge expects.
v10:
* Add changelog to the commit message
v8 -> v9:
* No changes
v7:
* Set atomic state hooks explicitly
v4 -> v6:
* Not part of the series
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)
v2:
* Adjust things to match the new bus-format negotiation approach
