This struct was just representing encoder information, it was a member of struct exynos_drm_encoder, so any code trying to access encoder data would have to go through the encoder struct, get the display struct and then get the data it want.

During this patchset we also realized that the only data exynos_drm_encoder needs to store is the drm_encoder parent and the exynos_drm_encoder_ops.

exynos_dp_commit() was getting called twice by exynos encoder core, once inside the .enable() call and another time by .commit() itself.

The remove of the second call caused the wake of a bug, the operations orders inside exynos_dp_commit was wrong and we had to move exynos_dp_start_video() to be the last operation in there.

This functions was just hiding the encoder and connector creation in a way that was less clean than if we get rid of it. For example, exynos_encoder ops had .create_connector() defined only because we were handing off the encoder and connector creation to exynos_drm_create_enc_conn(). Without this function we can directly call the create_connector function internally in the code, without the need of any vtable access.

It also does some refactoring in the code like creating a bind function for dpi devices.
