Pull crypto fixes from Herbert Xu:
"This fixes the following issues:
API:
- A large number of bug fixes for the af_alg interface, credit goes
to Dmitry Vyukov for discovering and reporting these issues.
Algorithms:
- sw842 needs to select crc32.
- The soft dependency on crc32c is now in the correct spot.
Drivers:
- The atmel AES driver needs HAS_DMA.
- The atmel AES driver was a missing break statement, fortunately
it's only a debug function.
- A number of bug fixes for the Intel qat driver"

Depending on its hardware version, the AES IP provides either a 16 or a
32 bit counter. However the CTR mode expects the size of the counter to be
the same as the size of the cipher block, ie 128 bits for AES.

This patch only creates sections to regroup functions by usage.
This will help to integrate the GCM support patch later by making the
difference between shared/common and specific code. Hence current
sections are:
- Shared functions: common code which will be reused by the GCM support.
- CPU transfer: handles transfers monitored by the CPU (PIO accesses).
- DMA transfer: handles transfers monitored by the DMA controller.
- AES async block ciphers: dedicated to the already supported block ciphers
- Probe functions: used to register all crypto algorithms.

This patch totally reworks data transfer.
1 - DMA
The new code now fully supports scatter-gather lists hence reducing the
number of interrupts in some cases. Also buffer alignments are better
managed to avoid useless copies.
2 - CPU
The new code allows to use PIO accesses even when transferring more than
one AES block, so futher patches could tune the DMA threshold
(ATMEL_AES_DMA_THRESHOLD).
Moreover, CPU transfers now have a chance to be processed synchronously,
hence reducing the latency by avoiding context switches when possible
(less interrupts to process, less scheduling of the 'done' task).
Indeed the 'DATA READY' bit is polled only one time in the Interrupt
Status Register before enabling then waiting for the associated interrupt.
In some condition, this single poll is enough as the data have already
been processed by the AES hardware and so are ready.

This patch changes atmel_aes_handle_queue() to make it more generic.
The function argument is now a pointer to struct crypto_async_request,
which is the common base of struct ablkcipher_request and
struct aead_request.
Also this patch introduces struct atmel_aes_base_ctx which will be the
common base of all the transformation contexts.
Hence the very same queue will be used to manage both block cipher and
AEAD requests (such as gcm and authenc implemented in further patches).

This patch changes the signature of atmel_aes_write_ctrl() to make it more
generic. This will be used by future patches when implementing new block
cipher modes such as GCM.
Especially atmel_aes_hw_init() is now called outside
atmel_aes_write_ctrl(): this allows to call atmel_aes_write_ctrl() many
times, still initializing the hardware only once.
Indeed, the support of GCM will require to update the Mode Register and
the IV when processing a single request.
