[PATCH] tools/testing/cxl: Remove cxl_test modulo math loading messages

[alison.schofield@intel.com]

From: Alison Schofield <alison.schofield@intel.com>

Commit "cxl/acpi: Support CXL XOR Interleave Math (CXIMS)" added
a module parameter to cxl_test for the interleave_arithmetic option.
In doing so, it also added this dev_dbg() message describing which
option cxl_test used during load:
"[  111.743246] (NULL device *): cxl_test loading modulo math option"

That "(NULL device *)" has raised needless user concern and the info
emitted can be discovered elsewhere.

Remove the dev_dbg() messages and make the module_param readable via
sysfs in case a lookup is wanted.

The default option is for standard modulo arithmetic, so when the
interleave_arithmetic param is not present in sysfs, the cxl_test
module is using standard modulo arithmetic.
