Dave Liu 5b0055547f 83xx: Fix some bugs in spd sdram code ...

1. RD_TO_PRE missed to add the AL, and need min 2 clocks for
  tRTP according to DDR2 JEDEC spec.
2. WRTORD - tWTR need min 2 clocks according to DDR2 JEDEC spec.
3. add the support of DDR2-533,667,800 DIMMs
4. cpo
5. make the AL to min to gain better performance.

The Micron MT9HTF6472CHY-667D1 DIMMs test passed on
MPC837xEMDS platform at 266MHz/333MHz/400MHz data rate.
