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.
