[CRYPTO] drivers: Remove obsolete block cipher operations
This patch removes obsolete block operations of the simple cipher type from drivers. These were preserved so that existing users can make a smooth transition. Now that the transition is complete, they are no longer needed. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
