MLK-13509 mx7ulp_evk: Update DDR script to v1.2

DDR script is updated to v1.2 for EVK board to fix DQS gating issue
and add pre-charge .That DQS sampling may have problem after we enabling
the SDE_0/SDE_1 in MDCTL.

Changes:
  -Issue a Precharge-All command prior to the MRW Reset command.
      setmem /32 0x40AB001C = 0x00008050  // [MMDC_MDSCR]  precharge all to CS0
  -Based on V1.1, move the "Read DQS Gating Disable" to the step after "MR setting",
   to avoid potential DDR initializaiton failures (especially in Plugin Mode).
