Add logic to compute MSS_MRW_NVDIMM_SLOT_POSITION for ZZ
There are a variety of ways to number dimms. For NVDIMMs there
is a system property that defines which positions we are allowed
to install the dimms in (ATTR_MSS_MRW_NVDIMM_PLUG_RULES). Because
of the inconsistent numbering schemes we have explicitly defined
a new attribute on the dimm that corresponds to the system plug
rules.
