It is already marked as Obsolete in MAINTAINERS. The cxlflash driver has received minimal maintenance for some time, and the CAPI Flash hardware that uses it is no longer commercially available. Add a warning message on probe and change Kconfig to label the driver as deprecated and not build the driver by default.
