Integrate crypto_engine into CAAM, to make use of the engine queue.
Add support for SKCIPHER 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.
This changes the return codes for enqueuing a request:
-EINPROGRESS if OK, -EBUSY if request is backlogged (via
crypto-engine), -ENOSPC if the queue is full, -EIO if it
cannot map the caller's descriptor.
The requests, with backlog flag, will be listed into crypto-engine
queue and processed by CAAM when free. Only the backlog request are
sent to crypto-engine since the others can be handled by CAAM, if free,
especially since JR has up to 1024 entries (more than the 10 entries
from crypto-engine).
