arm64: crypto: add NEON accelerated XOR implementation
This is a NEON acceleration method that can improve performance by approximately 20%. I got the following data from the centos 7.5 on Huawei's HISI1616 chip: [ 93.837726] xor: measuring software checksum speed [ 93.874039] 8regs : 7123.200 MB/sec [ 93.914038] 32regs : 7180.300 MB/sec [ 93.954043] arm64_neon: 9856.000 MB/sec [ 93.954047] xor: using function: arm64_neon (9856.000 MB/sec) I believe this code can bring some optimization for all arm64 platform. thanks for Ard Biesheuvel's suggestions.
