and delete the x86 specific version.

'u128' currently used for CTR mode is on little-endian 'long long' swapped
and would require extra swap operations by SSE/AVX code. Use of le128
instead of u128 allows IV calculations to be done with vector registers
easier.

Initialization of cra_list is currently mixed, most ciphers initialize this
field and most shashes do not. Initialization however is not needed at all
since cra_list is initialized/overwritten in __crypto_register_alg() with
list_add(). Therefore perform cleanup to remove all unneeded initializations
of this field in 'arch/x86/crypto/'.

Now that serpent-sse2 glue code has been made generic, it can be split to
separate module.

Block cipher implementations in arch/x86/crypto/ contain common glue code that
is currently duplicated in each module (camellia-x86_64, twofish-x86_64-3way,
twofish-avx, serpent-sse2 and serpent-avx). This patch prepares serpent-sse2
glue into generic glue code for all 128bit block ciphers to use in
arch/x86/crypto.

Rename serpent-avx assembler functions so that they do not collide with
serpent-sse2 assembler functions when linking both versions in to same
kernel image.

use single function ablk_init to reduce object size.

LRW/XTS patches for serpent-sse2 forgot to add this. CRYPTO_TFM_REQ_MAY_SLEEP
should be cleared as sleeping between kernel_fpu_begin()/kernel_fpu_end() is
not allowed.
