This commit simplifies the validate() and configure() calls in the
pipeline handler in a number of ways:
- Only pass the RPiCameraConfiguration structure into platformValidate()
and platformConfigure().
- Determine the V4L2DeviceFormat structure fields for all streams in
validate(), cache them and reuse in configure() instead of
re-generating this structure multiple times.
- Use the recently added updateStreamConfig() and toV4L2DeviceFormat()
helpers to populate fields in the V4L2DeviceFormat and
StreamConfiguration structures to reduce code duplication.
