kernel: ocf: add missing kernel dependencies

OCF_CRYPTOSOFT uses both symbols form crypto_hash and crypto_blkcipher,
so let it select these through kernel config.

Fixes the following build error:

ERROR: "crypto_alloc_ahash" [crypto/ocf/cryptosoft.ko] undefined!
ERROR: "crypto_ahash_digest" [crypto/ocf/cryptosoft.ko] undefined!
ERROR: "crypto_ahash_setkey" [crypto/ocf/cryptosoft.ko] undefined!
make[6]: *** [__modpost] Error 1
make[5]: *** [modules] Error 2
