[PATCH v8 10/12] drm/bridge: panel: Propage bus format/flags

[Boris Brezillon]

So that the previous bridge element in the chain knows which input
format the panel bridge expects.

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
