ASoC: cros_ec_codec: Remove unnecessary selection of CRYPTO

The only crypto-related functionality this codec uses is the sha256()
function, which is provided by CRYPTO_LIB_SHA256.  Originally
CRYPTO_LIB_SHA256 was visible only when CRYPTO; however, that was fixed
years ago and the libraries can now be selected on their own.

So, remove the unnecessary selection of CRYPTO.
