struct exynos_drm_encoder was justing wrapping struct drm_encoder, it had
only a drm_encoder member and the internal exynos_drm_encoders ops that
was directly mapped to the drm_encoder helper funcs.
So now exynos DRM uses struct drm_encoder directly, this removes
completely the struct exynos_drm_encoder.
v2: add empty .mode_fixup() and .mode_set() to DSI and DPI to avoid null
pointer.

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.

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.

In case there are multiple pipelines and deferred probe occurs, only components
of the first pipeline were bound. As a result only one pipeline was available.
The main cause of this issue was dynamic generation of component match table -
every component driver during probe registered itself on helper list, if there
was at least one pipeline present on this list component match table were
created without deferred components.
This patch removes this helper list, instead it creates match table from
existing devices requiring exynos_drm KMS drivers. This way match table do not
depend on probe/deferral order and contains all KMS components.
As a side effect patch makes the code cleaner and significantly smaller.

Run dpms operations through the atomic intefaces. This basically removes
the .dpms() callback from econders and crtcs and use .disable() and
.enable() to turn the crtc on and off.
v2: Address comments by Joonyoung:
- make hdmi code call ->disable() instead of ->dpms()
- do not use WARN_ON on crtc enable/disable
v3: - Fix build failure after the hdmi change in v2
- Change dpms helper of ptn3460 bridge
v4: - remove win_commit() call from .enable()
v5: - move .atomic_check() to the atomic PageFlip patch, and transform it
in .atomic_begin()

exynos_drm_display is used by internal Exynos DRM framework for
representing encoder:connector pair. As it should be mapped 1:1 to hdmi
private context it seems more reasonable to embed it directly in that context.
As a result further code simplification will be possible.
Moreover it will be possible to handle multiple hdmi devices in the system.
