functions to support AEAD ciphers in the next
patches.

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 fixes a type mismatch error that I accidentally
introduced when I moved and refactored the dynamic_contents
helpers.

The crypto engine supports more than just aes-cbc. This patch
enables the remaining AES block cipher modes that pass the
testmanager's test vectors.

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.

The driver had a union dynamic_sa_contents in place that
described the meaning of the bits in the sa_contents
variable.

This patch adds support for AMCC ppc4xx security device driver. This is the
initial release that includes the driver framework with AES and SHA1 algorithms
support.
The remaining algorithms will be released in the near future.
