Introduce a new video device structure representing a device in a
video pipeline. Each video device embeds a pointer to its "source"
device and other "video" characteristics.
This structure give the video framework an access to all video features
of the device and a hierachical view of the video pipeline that the
device belongs to.

The Chip ID field of the GC2145 was assumed to be 0x2155, but sensors
with Chip ID 0x2145 are still present. Rework how chip IDs verification
is done slightly and add support for both.

video_format_cap needs to be terminated with a NULL entry
to allow looping over the formats.

The video_stream_start/stop() APIs are counter-symetric and have
the same function signature. Also, the implementation logic for
those driver APIs is generally the same. Merge them to save memory
and code lines.
For the sake of simplicity, still keep the user APIs to preserve
backward compatibility with downstream applications.

Remove the unnecessary video-controls header included in video.h.
Drivers, applications should explicitly include it when needed.

This aims to make the code more linear by having the for loop
validates the input format rather than search for a match.

After the error code is checked to be zero, it is possible to return 0
explicitly to help with readability. Also, when available, forward the
return code from the failing function instead of a locally chosen error
code like -EIO.

While applying the format, the pixel format and drv_data->fmt were set
immediately, and the resolution was set only if it had a matching
entry on the "caps".
This commit makes sure the requested format matches the caps before
applying the format as well as drv_data->fmt. This does not guards
against partial failure (i.e. only pixelformat set and not
resolution).

Add VGA and QVGA resolution support to enable
usage of gc2145 sensor by smaller ram capable devices.
