Is this preprocessor needed? Unless something causes a compilation error on the non-CXL case, I would prefer adapting the check above:

```
    /* If there are no CXL nodes, we are done */
    if (!CONFIG(SOC_INTEL_HAS_CXL) || num_cxlnodes == 0)
    	return;
```

Is there any Xeon-SP platform that is not NUMA?
