crypto: skcipher - add helper for simple block cipher modes
The majority of skcipher templates (including both the existing ones and
the ones remaining to be converted from the "blkcipher" API) just wrap a
single block cipher algorithm. This includes cbc, cfb, ctr, ecb, kw,
ofb, and pcbc. Add a helper function skcipher_alloc_instance_simple()
that handles allocating an skcipher instance for this common case.
