The AVX2 implementation also uses BMI2 instructions,
but doesn't test for their availability. The assumption
that AVX2 and BMI2 always go together is false. Some
Haswells have AVX2 but not BMI2.

Commit a710f761f (crypto: sha256_ssse3 - add sha224 support) attempted to add
MODULE_ALIAS for SHA-224, but it ended up being "sha384", probably because
mix-up with previous commit 340991e30 (crypto: sha512_ssse3 - add sha384
support). Patch corrects module alias to "sha224".

Add sha224 implementation to sha256_ssse3 module.
This also fixes sha256_ssse3 module autoloading issue when 'sha224' is used
before 'sha256'. Previously in such case, just sha256_generic was loaded and
not sha256_ssse3 (since it did not provide sha224). Now if 'sha256' was used
after 'sha224' usage, sha256_ssse3 would remain unloaded.

We added glue code and config options to create crypto
module that uses SSE/AVX/AVX2 optimized SHA256 x86_64 assembly routines.
