crypto: ghash - Add GHASH digest algorithm for GCM
GHASH is implemented as a shash algorithm. The actual implementation is copied from gcm.c. This makes it possible to add architecture/hardware accelerated GHASH implementation. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
