cxl: Add callback to parse the DSMAS subtables from CDAT
Provide a callback function to the CDAT parser in order to parse the
Device Scoped Memory Affinity Structure (DSMAS). Each DSMAS structure
contains the DPA range and its associated attributes in each entry. See
the CDAT specification for details. The device handle and the DPA range
is saved and to be associated with the DSLBIS locality data when the
DSLBIS entries are parsed. The xarray is a local variable. When the
total path performance data is calculated and storred this xarray can be
discarded.
