Integrate crypto_engine framework into CAAM, to make use of the engine queue. Added support for SKCIPHER, HASH, RSA and AEAD algorithms. This is intended to be used for CAAM backlogging support. The requests, with backlog flag (e.g. from dm-crypt) will be listed into crypto-engine queue and processed by CAAM when free. For better performance, crypto-engine software queue is bypassed, if empty, and the request is sent directly to hardware. If this returns -ENOSPC, the request is transferred to crypto-engine and let it handle it. While here, I've also made some refactorization. Patch #1, adds a helper function - akcipher_request_cast, to get an akcipher_request struct from a crypto_async_request struct. Patches #2 - #5 include some refactorizations on caamalg, caamhash and caampkc. Patches #6, #7 change the return code of caam_jr_enqueue function to -EINPROGRESS, in case of success, -ENOSPC in case the CAAM is busy, -EIO if it cannot map the caller's descriptor and add a new enqueue function for no backlogging requests. Also, to keep each request information, like backlog flag, a new struct is passed as argument to enqueue functions. Patches #8 - #12 integrate crypto_engine into CAAM, for SKCIPHER/AEAD/RSA/HASH algorithms.
