I don't know that this would make sense. The mx6_ddr_sysinfo shouldn't
be affected by calibration and the mx6_mmdc_calibration structure
would not be used if you are using auto-calibration.

In fact, I recommend an additional patch that will call the
auto-calibration functions in mx6_ddr3_cfg if it is passed a NULL for
mx6_ddr_calibration.
