drm: atmel-hlcdc: move output mode selection in CRTC implementation
In order to support multiple outputs we need to move the output mode selection to the CRTC object, so that the output validity check can be done against the drm_atomic_state. If the connectors selected by a specific mode setting are requiring incompatible bus format the atomic operation is aborted (->atomic_check() returns -EINVAL). In order to implement that, we need to define our own CRTC state and overload default ->reset(), ->atomic_duplicate_state() and ->atomic_destroy_state() functions.
