MLK-17257-2: drm: imx: dcss: use the WRSCL/RDSRC modules

This patch makes the necessary changes so that, for downscaling ratios
more than 3:1 and up to 7:1 (for video) and 5:1 (for graphics), the
WRSCL/RDSRC path will be used. This way the DRAM bandwidth will be lower
and spread evenly across the frame time.
