crypto: ghash-generic - move common definitions to a new header file
Move common values and types used by ghash-generic to a new header file so drivers can directly use ghash-generic as a fallback implementation. Fixes: cc333cd68dfa ("crypto: vmx - Adding GHASH routines for VMX module") Cc: stable@vger.kernel.org Signed-off-by: Marcelo Cerri <marcelo.cerri@canonical.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
