From: Dan Williams <dan.j.williams@intel.com>
Replace IS_ENABLED(CONFIG_CXL_REGION) with IS_ENABLED(CONFIG_DEV_DAX_CXL)
so that HMEM only defers Soft Reserved ranges when CXL DAX support is
enabled. This makes the coordination between HMEM and the CXL stack more
precise and prevents deferral in unrelated CXL configurations.
