Update following DDR related settings for T1040QDS -Correct number of chip selects to two as t1040qds supports two Chip selects. -Update board_specific_parameters udimm structure with settings derived via calibration. -Reduced I2C speed to 50KHz as DDR-SPD does not get reliably read at 400KHz.
Verified the updated settings to be working fine with dual-ranked Micron, MT18KSF51272AZ-1G6 DIMM at data rate 833MT/s, 1333MT/s and 1600MT/s.
