Rank Offset for calculating RANK. This corresponds to the first logical rank on
the DIMM. The rank offset is always programmed to 0 for the DIMM 0 DOD
registers. (DIMM 0 rank offset is always 0.) DIMM 1 DOD rank offset is either 4
for two DIMMs per channel or 2 if there are three DIMMs per channel. DIMM2
DOD rank offset is always 4 as it is only used in three DIMMs per channel case.
