nb/i945/raminit: Use common ddr2 decode functions

This simplifies computing dram timings a lot.

This removes computation of rank size based on columns, rows,
banks,... and uses the information in SPD byte 31.
The result of this is that dimms with multiple asymmetric ranks are
not supported anymore. These however are very rare and most likely
never tested on this platform.
