The hmac algorithms state, that keys larger than the key size should be
hashed with the underlying hash algorithms and then those hashes are to
be used as keys. This patch implements this. In order to avoid allocating
a descriptor during setkey, a shash_desc pointer is added to the context.
Another issue for multithreaded callers is the shared temp array.
The temp array is static and as such would be shared among multithreaded
callers, which obviously would neither work nor produce correct results.
The temp array (4k size) is moved to the context and since the size of
the context is limited, it can only be defined as pointer otherwise the
initialisation of the hash algorithm fails.
The allocations and freeing of both the temp and the desc pointer in the
context are done by implementing cra_init and cra_exit functions for
the hmac algorithms.
Also improved indentation in some areas.

The algorithms sha1, sha1_hmac and md5_hmac all use ENDI=1. The md5
algorithm uses ENDI=0 and the endian_swap methods to reverse the
endianess switch by using user CPU time, which is unnecessary overhead.
Danube and AR9 devices do not set endianess for SHA1, so is done for
MD5.
Furthermore the patch replaces endian_swap with le32_to_cpu for md5 and
md5 hmac algorithms and removes endian_swap for them.
The init functions initialize the algorithm in the hardware. The lock is
not used to write to the control register. If another thread calls
another hash algo before update or final, the result will be wrong.
Therefore move the algorithm init to the lock protected sections in the
transform or final methods.
Setting the hw key for the hmac algorithms is now done from within the
lock protected sections in their final methods. The lock protecting is
removed from the _hmac_setkey_hw functions.
In final for md5 and sha1 the lock section is removed, because all the
work was already done in transform (which is called from final). As such
only copying the hash to the output is required.
MD5 and MD5_HMAC produce 16 byte hashes (4 DWORDS) only, therefor
writing register D5R to the hash output is removed for MD5_HMAC.

All hash algorithms use the same base IFX_HASH_CON to access the hash unit.
Parallel threads should not be able to call different hash algorithms and
therefor a global lock is required.
Fixed linker warning, that md5_hmac_init, md5_hmac_update and
md5_hmac_final are static export symbols. The export symbols are not
required, because the functions are exposed using shash_alg structure.

Even if the minimum blocksize is set to 16 (AES_BLOCK_SIZE), the crypto
manager tests pass 499 bytes of data to the aes-ctr encryption, from
which only 496 bytes are actually encrypted.
Reading the comment regarding the minimum blocksize, it only states that
it's the "smallest possible unit which can be transformed with this
algorithm". Which doesn't necessarily mean, the data have to be a
multiple of the minimal blocksize.
All kernel hardware crypto driver enforce a minimum blocksize of 1,
which perfect fine works for the lantiq data encryption unit as well.
Lower the blocksize limit to 1, to process not padded data as well.
In AES for processing the remaining bytes, uninitialized pointers
were used.
This patch fixes using uninitialized pointers and wrong offsets.

When handling non-aligned remaining data (not padded to 16 byte
[AES_BLOCK_SIZE]), a full 16 byte block is read from the input buffer
and written to the output buffer after en-/decryption.
While code already assumes that an input buffer could have less than 16
byte remaining, as it can be seen by the code zeroing the remaining
bytes till AES_BLOCK_SIZE, the full AES_BLOCK_SIZE is read.
An output buffer size of a multiple of AES_BLOCK_SIZE is expected but
never validated.
To get rid of the read/write behind buffer, use a temporary buffer when
dealing with not padded data and only write as much bytes to the output
as we read.
Do not memcpy directly to the register, to make used of the endian swap
macro and to trigger the crypto start operator via the ID0R to trigger
the register. Since we might need an endian swap for the output in
future, use a temporary buffer for the output as well.
The issue could not be observed so far, since all caller of ifx_deu_aes
will ignore the padded (remaining) data. Considering that the minimum
blocksize for the algorithm is set to AES_BLOCK_SIZE, the behaviour
could be called expected.
