crypto: camellia - add AES-NI/AVX/x86_64 assembler implementation of camellia cipher

Browse Source 
This patch adds AES-NI/AVX/x86_64 assembler implementation of Camellia block
cipher. Implementation process data in sixteen block chunks, which are
byte-sliced and AES SubBytes is reused for Camellia s-box with help of pre-
and post-filtering.

Patch has been tested with tcrypt and automated filesystem tests.

tcrypt test results:

Intel Core i5-2450M:
