In csc_set_coeff() we were previously checking if the format type was V4L2_BUF_TYPE_VIDEO_OUTPUT or V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE as a mean to figure out if the format was multiplanar or not. This was not entirely accurate as the format type could also be a CAPTURE type instead. Fix this by removing the 'switch' construct and replacing them with "if (V4L2_TYPE_IS_MULTIPLANAR(type))" instead.
