Ard Biesheuvel 2dde374e1f crypto: arm64/crct10dif - add non-SIMD generic fallback
The arm64 kernel will shortly disallow nested kernel mode NEON, so
add a fallback to scalar C code that can be invoked in that case.

Ard Biesheuvel 6ef5737f39 crypto: arm64/crct10dif - port x86 SSE implementation to arm64
This is a transliteration of the Intel algorithm implemented
using SSE and PCLMULQDQ instructions that resides in the file
arch/x86/crypto/crct10dif-pcl-asm_64.S, but simplified to only
operate on buffers that are 16 byte aligned (but of any size)
