We get a newly introduced harmless warning when CONFIG_CRYPTO is disabled:

warning: (TCG_TPM && TRUSTED_KEYS && IMA) selects CRYPTO_HASH_INFO which has unmet direct dependencies (CRYPTO)

This adds another select to avoid the warning, consistent with other users
of the crypto code.

Fixes: c1f92b4b04ad ("tpm: enhance TPM 2.0 PCR extend to support multiple banks")
