    kernel: crypto: add SHA512 ARM64 ASM optimized module
    
    Kernel has an ASM optimized version of SHA512 that was ported from
    OpenSSL, so lets package it as it provides significant perfomance
    improvement compared to the generic implementation.
    
    There is a Cryptographic Extension based version as well, but that relies
    on ARMv8.2 ISA which I am not aware any of the OpenWrt supported SoC-s use.
