loop over dimms and save maximal timings

i945 supports two DIMMs, in two configurations:

single channel with two DIMMs
dual channel with one DIMM per channel

In practice dual channel mainboards have their SPD at 0x50/0x52 whereas single channel configurations have their SPD at 0x50/0x51.

The capability register knows a lot about the channel configuration but for now we stick with the information we gather via SPD.

There are 5 different possible populations for a DIMM socket: 0. x16 double ranked (X16DS)

x8 double ranked (X8DS)
x16 single ranked (X16SS)
x8 double stacked (X8DDS)
Unpopulated
