While all consumers of the API have been converted long ago, some producers of the ablkcipher remain, forcing us to keep the ablkcipher support routines alive, along with the matching code to expose [a]blkciphers via the skcipher API. So switch this driver to the skcipher API, allowing us to finally drop the ablkcipher code in the near future.
