When running NXP 4.1 kernel with U-Boot mainline we observe a hang when going into the lowest operational point of cpufreq.
Comparing the DDR calibration values against NXP U-Boot showed that the values were incorrect.
Adjust the calibration values so that we can avoid such system hang.

After running more tests I still get the hang sometimes, so we still need to review the DDR SPL settings.
