crypto: gf128mul - make unselectable by user

There's no reason for users to select CONFIG_CRYPTO_GF128MUL, since it's
just some helper functions, and algorithms that need it select it.

Remove the prompt string so that it's not shown to users.

-         an external module that requires these functions.
