mpc85xx/t208xqds: Adjust DDR timing parameters
Adjust timing for dual-rank UDIMM, verified on M3CQ-8GHS3C0E for speed of 1066, 1333, 1600, 1866MT/s. The 1866 timing is copied to 2133 timing in case such DIMM comes available. Also update single-rank 1866 timing. Enable interactive debugging as well. Signed-off-by: York Sun <yorksun@freescale.com> CC: Shengzhou Liu <Shengzhou.Liu@freescale.com>
