crypto: crypto4xx - simplify sa and state context acquisition

Thanks to the big overhaul of crypto4xx_build_pd(), the request-local
sa_in, sa_out and state_record allocation can be simplified.

There's no need to setup any dma coherent memory anymore and
much of the support code can be removed.

crypto: crypto4xx - overhaul crypto4xx_build_pd()

This patch overhauls and fixes code related to crypto4xx_build_pd()

* crypto4xx_build_pd() did not handle chained source scatterlist.
This is fixed by replacing the buggy indexed-access of &src[idx]
with sg_next() in the gather array setup loop.

* The redundant is_hash, direction, save_iv and pd_ctl members
in the crypto4xx_ctx struct have been removed.
- is_hash can be derived from the crypto_async_request parameter.
- direction is already part of the security association's
bf.dir bitfield.
- save_iv is unused.
- pd_ctl always had the host_ready bit enabled anyway.
(the hash_final case is rather pointless, since the ahash
code has been deactivated).

* make crypto4xx_build_pd()'s caller responsible for converting
the IV to the LE32 format.

* change crypto4xx_ahash_update() and crypto4xx_ahash_digest() to
initialize a temporary destination scatterlist. This allows the
removal of an ugly cast of req->result (which is a pointer to an
u8-array) to a scatterlist pointer.

* change crypto4xx_build_pd() return type to int. After all
it returns -EINPROGRESS/-EBUSY.

* fix crypto4xx_build_pd() thread-unsafe sa handling.

crypto: crypto4xx - use the correct LE32 format for IV and key defs

The hardware expects that the keys, IVs (and inner/outer hashes)
are in the le32 format.

This patch changes all hardware interface declarations to use
the correct LE32 data format for each field.

In order to pass __CHECK_ENDIAN__ checks, crypto4xx_memcpy_le
has to be honest about the endianness of its parameters.
The function was split and moved to the common crypto4xx_core.h
header. This allows the compiler to generate better code if the
sizes/len is a constant (various *_IV_LEN).

Please note that the hardware isn't consistent with the endiannes
of the save_digest field in the state record struct though.
The hashes produced by GHASH and CBC (for CCM) will be in LE32.
Whereas md5 and sha{1/,256,...} do not need any conversion.

This patch refactors and moves the dynamic_contents helper
functions into the crypto4xx_sa.h header file.

* get_dynamic_sa_iv_size is no longer needed, as the cryptoapi
provides the required IV size information as well.

* refactor the function declarations to use the a pointer to the
dynamic_sa_contents union, instead of the crypto4xx_ctx.

* rename get_dynamic_sa_offset_key_field to get_dynamic_sa_key_field.
It returns the pointer to the key directly.
