ACPI: HMAT / cxl: Add retrieval of generic port coordinates for both access classes
Update acpi_get_genport_coordinates() to allow retrieval of both access
classes of the 'struct access_coordinate' for a generic target. The update
will allow CXL code to compute access coordinates for both access class.
