MLK-13508-1 mx6sllevk: Update DDR script to v2.2

DDR script is updated to v2.2 to fix potential DQS gating issue. That DQS sampling
may have problem after enabling the SDE_0/SDE_1 in MDCTL.

Changes:
    -Based on V2.1.1, move the "Read DQS Gating Disable" to the step after
     "MR setting", to avoid potential DDR initializaiton failures
     (especially in Plugin Mode).
