The driver does not expose controls directly and thus does not need
a controls handler for its own use.
Controls attached to subdevs used to be exposed that way, however this
can easily lead to issue when multiple subdevs attached to the same
v4l2 device expose the same controls. Subdev controls should be set
through each individual subdev node instead.

Merge contents of structs sun6i_csi and sun6i_csi_dev into a main
sun6i_csi_device structure holding a sun6i_csi_v4l2 struct for things
related to v4l2, as well as the already-existing sun6i_csi_video and
sun6i_csi_config which are left unchanged.
This mostly simplifies accessing stuff by having a single main
structure accessible to every part of the code instead of a private
definition.
Also solve some kerneldoc warnings by describing return codes while
at it.

HFI_VERSION_1XX uses HFI_BUFFER_OUTPUT not HFI_BUFFER_OUTPUT2 for decoder
buffers.
venus_helper_check_format() places a constraint on an output buffer to be
of type HFI_BUFFER_OUTPUT2. HFI_1XX uses HFI_BUFFER_OUTPUT though.
Switching to the logic used in venus_helper_get_out_fmts() first checking
for HFI_BUFFER_OUTPUT and then HFI_BUFFER_OUTPUT2 resolves on HFI_1XX.

[Note: the code is mostly from Laurent but the patch description is from Tomi]
The media_pipeline_start() and media_pipeline_stop() functions use the
media graph walk API to traverse the graph and validate the pipeline.
The graph walk traverses the media graph following links between the
entities.
Also, while the pipeline can't change between the start and stop calls,
the graph is walked again from scratch at stop time, or any time a
driver needs to inspect the pipeline.
With the upcoming multiplexed streams support we will need a bit more
intelligent pipeline construction, as e.g. two independent streams may
be passing through a single entity via separate pads in which case
those pads should not be part of the same pipeline.
This patch essentially rewrites the media_pipeline_start/stop so that
a pipeline is defined as a set of pads instead of entities and the media
graph traversal considers the pad interdependencies when choosing which
links to follow.
Currently all the entity's pads are considered as interdependent. This
means that the behavior with all the current drivers stays the same, but
in the future we can define a more fine-grained pipeline construction.
Additionally the media pipeline's pads are cached at
media_pipeline_start() time, and re-used at media_pipeline_stop() which
avoid the need to re-walk the whole graph as the previous implementation
did.
Also, caching pads in the pipeline can serve in the future as the
foundation to provide a better API than the media graph walk to drivers
to iterate over pads and entities in the pipeline.
Note that the old media_pipeline_start/stop used the media graph walk
API. The new version does not use the media graph walk API, but instead
a new implementation.
There are two reasons for not changing the graph walk: it proved to be
rather difficult to change the graph walk to have the features
implemented in this patch, and second, this keeps the backward
compatibility of the graph walk as there are users of the graph walk API
The long term plan is that all the existing code would be converted to
use the new cached pipeline, thus allowing us to remove the graph walk.

Add new variant of media_pipeline_start(), media_pipeline_alloc_start().
media_pipeline_alloc_start() can be used by drivers that do not need to
extend the media_pipeline. The function will either use the pipeline
already associated with the entity, if such exists, or allocate a new
pipeline.
When media_pipeline_stop() is called and the pipeline's use count drops
to zero, the pipeline is automatically freed.

With the upcoming stream related improvements to the pipelines, the
pipelines are moved from media entities to media pads. As the drivers
currently use the pipelines with the entity based model, moving the
pipelines to pads will cause changes to the drivers.
However, most of the uses of media pipelines are related to a video
device (a DMA engine) with a single pad, and thus there's never a need
to support multiple pads in these use cases. We can avoid pushing the
complexities of the pad based model to the drivers by adding video
device wrappers for the pipeline related functions.
This patch adds a number of wrappers to media_pipeline functions, all of
which take a video_device as a parameter (instead of a media_entity),
and verify that there's just one pad.
