Without the base RSA code, we run into a link error:
ERROR: "rsa_parse_pub_key" [drivers/crypto/ccp/ccp-crypto.ko] undefined!
ERROR: "rsa_parse_priv_key" [drivers/crypto/ccp/ccp-crypto.ko] undefined!
Like the other drivers implementing RSA in hardware, this
can be avoided by always enabling the base support when we build
CCP.
Fixes: ceeec0afd6 ("crypto: ccp - Add support for RSA on the CCP")
