LS1021AQDS has a variant with DDR4 slot. This patch adds a new target for this variant and enables DDR4 support. RAW timing parameters are not added for DDR4. The board timing parameters are only tuned for single-rank 1600 and 1800MT/s with Micron DIMM 9ASF51272AZ-2G1A1 due to availability.

I accept this suggestion but will wait for the final name of the board. I used _D4 following T1040QDS_D4 because that board was named so.
