Jussi Kivilinna 0b95ec56ae crypto: camellia - add assembler implementation for x86_64 
Patch adds x86_64 assembler implementation of Camellia block cipher. Two set of
functions are provided. First set is regular 'one-block at time' encrypt/decrypt
functions. Second is 'two-block at time' functions that gain performance increase
on out-of-order CPUs. Performance of 2-way functions should be equal to 1-way
functions with in-order CPUs.

Patch has been tested with tcrypt and automated filesystem tests.

Tcrypt benchmark results:

AMD Phenom II 1055T (fam:16, model:10):
