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).
