For RGB24, in example, the component ordering on the wire as described by the CSI-2 specification matches the BGR888 format, while once stored in in memory by the CSIS receiver they match the RGB888 format. Add an additional .output field to struct csis_pix_format to allow propagating the correct format to the source pad after a format configuration on the sink. The change is only relevant for RGB24 but paves the way for further format translations in future.
