MLK-13508-2 mx6sllarm2: Update DDR script to v2.3

DDR scripts are updated to fix DQS gating issue commonly for LPDDR2 and LPDDR3. That DQS sampling may have problem after enabling the SDE_0/SDE_1 in MDCTL. Changes: -Based on V2.2, move the "Read DQS Gating Disable" to the step after "MR setting", to avoid potential DDR initializaiton failures (especially in Plugin Mode).
