Dave Jiang 117132edc6 cxl/test: Add support for qos_class checking
Set a fake qos_class to a unique value in order to do simple testing of
qos_class for root decoders and mem devs via user cxl_test. A mock
function is added to set the fake qos_class values for memory device
and overrides cxl_endpoint_parse_cdat() in cxl driver code.
