drm/komeda: Add komeda_build_layer_data_flow
build_layer_data_flow builds a input pipeline according to plane_state.
and in this initial stage only added this simplest pipeline usage:
Layer -> compiz
The scaler and layer_split will be added in the future.
v2:
- Rebase.
- Introduce struct komeda_data_flow_cfg
- Add a function komeda_component_validate_private to replace the MACRO
component_validate_private
