For DDR3 controller, the clk_adjust and wrlvl_start are platform-dependent. The best values should be picked up from the middle of all working combinations. This patch updates the table with confirmed values tested on Hynix dual-rank UDIMMs (HMT125U7BFR8C-H9) at 1300MT/s, 1200MT/s, 1000MT/s, 900MT/s, 800MT/s and Kingston quad-rank RDIMMs (KVR1333D3Q8R9S/4G) at 1300MT/s, 1200MT/s, 1000MT/s.
