[PATCH v10 10/12] drm/bridge: panel: Propage bus format/flags

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
