Add generic port support for the parsing of HMAT locality sub-table. The attributes will be added to the third array member of the hmem_attrs in order to not mix with the existing memory attributes it only provides the locality attributes from initator to the generic port targets and is missing the rest of the data from the actual memory device. The actual memory attributes will be updated when a memory device is attached and the locality information is calculated end to end.
