This patch adds support for the SHA-1 Secure Hash Algorithm for CPUs that have support for the SHA-1 part of the ARM v8 Crypto Extensions. It greatly improves sha-1 based operations, about 10x faster on iMX8M evk board. ~12ms vs ~165ms for a 20MiB kernel sha-1 verification. asm implementation is a simplified version of the Linux version (from Ard Biesheuvel).
