ANDROID: crypto: allow blkcipher walks over ablkcipher data
Add a function blkcipher_ablkcipher_walk_virt() which allows ablkcipher
algorithms to use the blkcipher_walk API to walk over their data. This
will be used by the HEH algorithm, which to support asynchronous ECB
algorithms will be an ablkcipher, but it also needs to make other passes
over the data.
