Subject: [PATCH v2 0/6] crypto: engine - Permit to enqueue all async requests

Hello

The current crypto_engine support only ahash and ablkcipher request.
My first patch which try to add skcipher was Nacked, it will add too many functions
and adding other algs(aead, asymetric_key) will make the situation worst.

This patchset remove all algs specific stuff and now only process generic crypto_async_request.

The requests handler function pointer are now moved out of struct engine and
are now stored directly in a crypto_engine_reqctx.

The original proposal of Herbert [1] cannot be done completly since the crypto_engine
could only dequeue crypto_async_request and it is impossible to access any request_ctx
without knowing the underlying request type.

So I do something near that was requested: adding crypto_engine_reqctx in TFM context.
Note that the current implementation expect that crypto_engine_reqctx
is the first member of the context.

The first patch is a try to document the crypto engine API.
The second patch convert the crypto engine with the new way,
while the following patchs convert the 4 existing users of crypto_engine.
Note that this split break bisection, so probably the final commit will be all merged.

Appart from virtio, all 4 latest patch were compile tested only.
But the crypto engine is tested with my new sun8i-ce driver.

Regards

Changes since V1:
- renamed crypto_engine_reqctx to crypto_engine_ctx
- indentation fix in function parameter
- do not export crypto_transfer_request
- Add aead support
- crypto_finalize_request is now static

Changes since RFC:
- Added a documentation patch
- Added patch for stm32-cryp
- Changed parameter of all crypto_engine_op functions from
	crypto_async_request to void*
- Reintroduced crypto_transfer_xxx_request_to_engine functions
