Add md5 sha1 sha256 support for crypto engine in rk3288.
This patch can't support multiple updatings because of limited of IC,
as result, it can't support import and export too.

As import and export are a required part of the API you have
to implement them or your algorithm can't even be reigstered.

If you the hardware cannot support them then your choices are
limited to a software fallback.

Cheers,

Ok! Thanks your comment.
I will add a software fallback like img-hash.c do
