media: cedrus: Use H264_SCALING_MATRIX only when required
Baseline, Main and Extended profiles are specified to not support a scaling matrix. Also, High profiles can optionally specify a scaling matrix, using SPS and PPS NAL units. To meet this expectation, applications are required to set the V4L2_CID_MPEG_VIDEO_H264_SCALING_MATRIX control and set the V4L2_H264_PPS_FLAG_SCALING_MATRIX_PRESENT flag only when a scaling matrix is specified for a picture. Implement this on cedrus, which has hardware support for this case.
