Rename static / file-local functions so that they do not conflict with
the functions declared in crypto/sha256.h.
This is a preparation patch for folding crypto/sha256.h into crypto/sha.h.

Replace all calls to may_use_simd() in the arm crypto code with
crypto_simd_usable(), in order to allow testing the no-SIMD code paths.

Almost all files in the kernel are either plain text or UTF-8 encoded. A
couple however are ISO_8859-1, usually just a few characters in a C
comments, for historic reasons.
This converts them all to UTF-8 for consistency.

Many shash algorithms set .cra_flags = CRYPTO_ALG_TYPE_SHASH. But this
is redundant with the C structure type ('struct shash_alg'), and
crypto_register_shash() already sets the type flag automatically,
clearing any type flag that was already there. Apparently the useless
assignment has just been copy+pasted around.
So, remove the useless assignment from all the shash algorithms.
This patch shouldn't change any actual behavior.

This removes all the boilerplate from the existing implementation,
and replaces it with calls into the base layer.

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):
bs b/u sha256-neon sha256-asm
16 16 x1.32 x1.19
64 16 x1.27 x1.15
64 64 x1.36 x1.20
256 16 x1.22 x1.11
256 64 x1.36 x1.19
256 256 x1.59 x1.23
1024 16 x1.21 x1.10
1024 256 x1.65 x1.23
1024 1024 x1.76 x1.25
2048 16 x1.21 x1.10
2048 256 x1.66 x1.23
2048 1024 x1.78 x1.25
2048 2048 x1.79 x1.25
4096 16 x1.20 x1.09

8192 4096 x1.85 x1.28
8192 8192 x1.85 x1.27
Where bs refers to block size and b/u to bytes per update.
