Since the Linux kernel commit:
69e39d40587b ("media: vimc: Implement get/set selection in sink")
the crop rectangle on the VIMC scaler sink pad needs to be
reset to match the requested format to avoid hitting a pipeline format
misconfiguration when the applied format is larger than the one
set in a previous capture session.
As the V4L2 specification is not clear on what the correct behaviour
is, if the crop rectangle should be reset automatically or not on a
set_fmt operation, momentary fix the pipeline handler to please the
driver and manually reset the crop rectangle.

Store the MediaDevice for the VIMC instance in the VimcCameraData class.
This will be used to check the media device version at runtime.

Expose the image stride which may be retrieved after a video device
has been configured. It may only be retrieved at that point as the
assignment of video devices takes place at this point.
In the future video devices should be assigned at configuration
validation time and the stride value retrieved at that point.

Use the sensor model to create the camera name. The resulting name
should still be "VIMC Sensor B", but prepares for support of Sensor A.

Pass the vimc IPA dummy configuration file to the IPA init() function.
This will be used by the IPA to validate the init() call.

Add a new IPASettings class to pass IPA initialization settings through
the IPAInterface::init() method. The settings currently only contain the
name of a configuration file, and are expected to be extended later.

Group AE, AWB, etc. controls together for accessibility.
Update descriptions for Contrast, Brightness, and Saturation controls.
Update the uvcvideo and vimc pipeline handlers to use the new
brightness, contrast and saturation units. UVC has no explicit units for
those controls, so map them with a best effort heuristic. For VIMC,
hardcode the control range based on knowledge of the driver
implementation for simplicity.

Call the IPA start()/stop() functions before/after the camera is
started. This makes sure the IPA functions properly once thread
management is moved into the start/stop interface.

Give a subdirectory to all pipeline handlers to make the structure of
the source tree more consistent. This will also simplify the
implementation of pipeline handlers selection at build time.
