[PATCH v2 0/3] media: imx-csi: cleanup media pipeline start

[Michael Tretter]

The imx media device currently assumes that there is only a single media
pipeline. However, the media graph has multiple imx capture devices.
These may be started separately on media pipelines if they don't cause
conflicts in the media graph.

Move the media pipeline from the media device to the capture devices to
properly track and handle multiple media pipelines for the imx-csi.
Refactor the code to start the media pipeline from the driver to help
the reader.
