Komeda driver treats KMS-CRTC/PLANE as user which will acquire pipeline
resources, but we still need to release the unclaimed resources.
crtc_atomic_check is the final check stage, so beside build a display data
pipeline according the crtc_state, but still needs to release/disable the
unclaimed pipeline resources.
v2: Rebase

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
