[media] s5p-fimc: Fix bytesperline value for V4L2_PIX_FMT_YUV420M format
Make sure bytesperline for Cb, Cr planes for V4L2_PIX_FMT_YUV420M format is half of the Y plane value, rather than having same bytesperline for all planes. While at it, simplify the bytesperline parameter handling by storing it when image format is set and returning those values when getting the format, instead of recalculating bytesperline from intermediate parameters.
