imx: mx6q DDR3 init: Fix tMRD MMDC1_MDCFG1.tMRD should be set to max(tMRD, tMOD) for DDR3. For all DDR3 speed bins: tMRD(min) = 4 nCK tMOD(min) = max(12 nCK, 15 ns) Hence, MMDC1_MDCFG1.tMRD should be set to max(12 nCK, 15 ns), which is 12 nCK at 532 MHz, encoded as 0xB in the bit-field MMDC1_MDCFG1[8:5].
