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.
Signed-off-by: Zain Wang <zain.wang@xxxxxxxxxxxxxx>
---
Changes in V4:
- remove CRYPTO_ALG_NEED_FALLBACK.
Changes in V3:
- add switch instead of multiple if.
Changes in V2:
- add some comments to code.
- fix some issues about zero message process.
