powerpc/t104xrdb: Update DDR initialization related settings
Update following DDR related settings for T1040RDB, T1042RDB_PI -Correct number of chip selects to two as t1040 supports two Chip selects. -Update board_specific_parameters udimm structure with settings derived via calibration. -Update ddr_raw_timing sructure corresponding to DIMM. -Set ODT to off. Typically on FSL board, ODT is set to 75 ohm, but on T104xRDB, on setting this , DDR instability is observed. Board-level debugging is in progress. Verified the updated settings to be working fine with dual-ranked Micron, MT18KSF51272AZ-1G6 DIMM at data rate 1600MT/s.
