[U-Boot] [PATCH v2 2/2] ARM: imx6: update 1GB DDR3 calibration for DHCOM i.MX6qd PDK

[U-Boot] [PATCH v2 2/2] ARM: imx6: update 1GB DDR3 calibration for DHCOM i.MX6qd PDK

[Ludwig Zenz]

The existing calibration values were found to be incorrect
in comparison to newly determined values.

The new values were generated with the help of 5 boards. They have
been determined with the NXP Utility 'DDR Stress Test (2.9.0)'.
