socket has no DCPMM DIMM
 Mode definitions: AD=App Direct Mode, MM=Memory Mode, AD+MM=Mixed
Mode
 For MM, general DDR4+DCPMM ratio is between 1:4 and 1:16. Excessive
capacity for DCPMM can be used for AD.
 For each individual population, rearrangements between channels are
allowed as long as the resulting population is consistent to Purley PDG rules
 For each individual population, the same DDR4 DIMM has to used in all slots,
as specified by the Purley PDG rules
 For each individual population, sockets are normally symmetric with
exceptions for 1 DCPMM per socket and 1 DCPMM per node case.
