ddr: update DGL parameters per CS

    - current DGL parameters were set to 2 CS.
    - in this patch, the DGL is configured according to the DGL number.
    - the DGL is per device therefore, it needs to be updated in each
      silicon configuration h file.

    Note: BC2 can work without ODT pin so RTT Write is used
          in order to save power.
