A comment in drivers/cxl/port.c refers to CONFIG_PROVE_CXL_LOCKING,
which was removed in commit 38a34e10768c ("cxl: Drop
cxl_device_lock()"). That commit switched CXL subsystem locking to
custom lock classes, which can be validated via the standard
CONFIG_PROVE_LOCKING option. Update the comment to reflect this.

Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.
