crypto: camellia - add AVX2/AES-NI/x86_64 assembler implementation of camellia cipher
Patch adds AVX2/AES-NI/x86-64 implementation of Camellia cipher, requiring 32 parallel blocks for input (512 bytes). Compared to AVX implementation, this version is extended to use the 256-bit wide YMM registers. For AES-NI instructions data is split to two 128-bit registers and merged afterwards. Even with this additional handling, performance should be higher compared to the AES-NI/AVX implementation.

+ Camellia cipher algorithm module (x86_64/AES-NI/AVX2).
+
+ Camellia is a symmetric key block cipher developed jointly
+ at NTT and Mitsubishi Electric Corporation.
+
+ The Camellia specifies three key sizes: 128, 192 and 256 bits.
