per the komeda driver design, A DRM-plane maps to komeda layer input
pipeline, so the plane->atomic_check will build a layer input pipeline
according to the plane_state. and with
get_state_and_set_user packed get_state and set_user into one function,
which get pipeline/component state for a specific pipeline/component, if
success set the user to it.

Add a debugfs node "register" and entry function dump_register to
dev/pipeline/component to register dump, then user can read
"/sys/kernel/debug/komeda/register" to get the register values via these

1. Added irq_handler/irq_enable/irq_disable to komeda_dev_func, then the
Komeda-CORE can control the HW irq via these chip function.
2. Install irq and register irq_handler to system by DRM, so once the IRQ
coming, the handling sequence is:
komeda_kms_irq_handler(int irq, void *data)
komeda_accemble_pipelines is for:
1. Verifing the component->supported_inputs according to the
pipeline->avail_components.
2. Generating component->supported_outputs.
