Without CONFIG_DEBUG_FS, we get a harmless warning:
drivers/crypto/axis/artpec6_crypto.c:352:23: error: 'dbgfs_root' defined but not used [-Werror=unused-variable]
This moves it into the #ifdef that hides the only user.
Fixes: a21eb94fc4d3 ("crypto: axis - add ARTPEC-6/7 crypto accelerator driver")
