[ Upstream commit c628e78899ff8006b5f9d8206da54ed3bb994342 ]
The CSID decodes the input data stream. When the input comes from the Test Generator the format of the stream is set on the source media pad. When the input comes from the CSIPHY the format is the one on the sink media pad. Use the proper format for each case.
