libcamera: pipeline: simple: Walk pipeline using subdev internal routing
When traversing the media graph to discover a pipeline from the camera
sensor to a video node, all sink-to-source paths inside subdevs are
considered. This can lead to invalid paths being followed, when a subdev
has restrictions on its internal routing.
The V4L2 API supports exposing subdev internal routing to userspace.
Make use of this feature, when implemented by a subdev, to restrict the
internal paths to the currently active routes. If a subdev doesn't
implement the internal routing operations, all source pads are
considered, as done today.
This change is needed to properly support multiple sensors with devices
such as the NXP i.MX8 ISI or the MediaTek i350 and i500 SENINF. Support
for changing routes dynamically will be added later when required.
