Sami Tolvanen f2f770d74a crypto: arm/sha256 - Add optimized SHA-256/224 
Add Andy Polyakov's optimized assembly and NEON implementations for
SHA-256/224.

The sha256-armv4.pl script for generating the assembly code is from
OpenSSL commit 51f8d095562f36cdaa6893597b5c609e943b0565.

Compared to sha256-generic these implementations have the following
tcrypt speed improvements on Motorola Nexus 6 (Snapdragon 805):

  8192  8192     x1.85        x1.27

Where bs refers to block size and b/u to bytes per update.
