crypto: x86/aria - implement aria-avx2
aria-avx2 implementation uses AVX2, AES-NI, and GFNI.
It supports 32way parallel processing.
So, byteslicing code is changed to support 32way parallel.
And it exports some aria-avx functions such as encrypt() and decrypt().
There are two main logics, s-box layer and diffusion layer.
These codes are the same as aria-avx implementation.
But some instruction are exchanged because they don't support 256bit
registers.
Also, AES-NI doesn't support 256bit register.
So, aesenclast and aesdeclast are used twice like below:
vextracti128 $1, ymm0, xmm6;
vaesenclast xmm7, xmm0, xmm0;
vaesenclast xmm7, xmm6, xmm6;
vinserti128 $1, xmm6, ymm0, ymm0;
