acpi: numa: Add setting of generic port system locality attributes

Add generic port support for the parsing of HMAT system locality sub-table.
The attributes will be added to the third array member of the access
coordinates in order to not mix with the existing memory attributes. It
only provides the system locality attributes from initiator to the
generic port targets and is missing the rest of the data to the actual
memory device.

The complete attributes will be updated when a memory device is
attached and the system locality information is calculated end to end.

Through hmat_update_target_attrs(), the best performance attributes will
be setup in target->coord.
