ada02b8463 imx: mx6q DDR3 init: Fix SDE_to_RST
MMDC1_MDOR.SDE_to_RST should be set to 200 µs according to the JEDEC
specification for DDR3. With a cycle of 15.258 µs, this gives 14 cycles encoded
as 0x10 for the bit-field MMDC1_MDOR[13:8].

aa53149e11 imx: mx6q DDR3 init: Fix tXPR
MMDC1_MDOR.tXPR should be set as specified for the JEDEC DDR3 timing tXPR.

For all DDR3 speed bins:
  tXPR(min) = max(5 nCK, tRFC(min) + 10 ns)
  tRFC(2 Gb) = 160 ns

All the users of mx6q_4x_mt41j128.cfg have a 2-Gb density (Micron
MT41J128M16HA-15E or SK hynix H5TQ2G63BFR-H9C for i.MX6Q SABRE Lite, and Micron
MT41K128M16JT-125:K for i.MX6 SABRE SD).

Hence, MMDC1_MDOR.tXPR should be set to max(5 nCK, 170 ns), which is 170 ns
and 91 nCK at 532 MHz, encoded as 0x5A in the bit-field MMDC1_MDOR[23:16].

6904e37746 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].
