[CRYPTO] sha: Add header file for SHA definitions
There are currently several SHA implementations that all define their own initialization vectors and size values. Since this values are idential move them to a header file under include/crypto. Signed-off-by: Jan Glauber <jang@de.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
