This change enables a more efficient way to check if the input and output formats use the same colorspace. With this change, we can eliminate the use of `v4l2_format_info()` in `rzg2l_cru_initialize_image_conv()` as the necessary details for the source and destination formats are already available through the `yuv` flag.
