This patch removes the last reference to hash and ablkcipher from
IPsec and replaces them with ahash and skcipher respectively.  For
skcipher there is currently no difference at all, while for ahash
the current code is actually buggy and would prevent asynchronous
algorithms from being discovered.

While converting ecryptfs over to skcipher I found that it needs
to pick a default key size if one isn't given.  Rather than having
it poke into the guts of the algorithm to get max_keysize, let's
provide a helper that is meant to give a sane default (just in
case we ever get an algorithm that has no maximum key size).

This patch saves the value of the internal hash register at the end of an
'update' operation then restores this value before starting the next
'update'. This way the driver can now properly handle context switches.

WARNING: only hardware versions from sama5d4x and later provide the
needed interface to update the internal hash value. Especially, sama5d3x
cannot implement this feature so context switches are still broken.

The 'done' tasklet handler used to check the 'BUSY' flag to either
finalize the processing of a crypto request which had just completed or
manage the crypto queue to start the next crypto request.

On request R1 completion, the driver calls atmel_sha_finish_req(), which:
1 - clears the 'BUSY' flag since the hardware is no longer used and is
    ready again to process new crypto requests.
2 - notifies the above layer (the client) about the completion of the
    asynchronous crypto request R1 by calling its base.complete()
    callback.
3 - schedules the 'done' task to check the crypto queue and start to
    process the next crypto request (the 'BUSY' flag is supposed to be
    cleared at that moment) if such a pending request exists.

However step 2 might wake the client up so it can now ask our driver to
process a new crypto request R2. This request is enqueued by calling the
atmel_sha_handle_queue() function, which sets the 'BUSY' flags then
starts to process R2.

If the 'done' tasklet, scheduled by step 3, runs just after, it would see
that the 'BUSY' flag is set then understand that R2 has just completed,
which is wrong!

So the state of 'BUSY' flag is not a proper way to detect and handle
crypto request completion.

This patch fixes this race condition by using two different tasklets, one
to handle the crypto request completion events, the other to manage the
crypto queue if needed.
