crypto: omap-aes - Fix registration of algorithms
Algorithms can be registered only once. So skip registration of algorithms if already registered (i.e. in case we have two AES cores in the system.) Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Signed-off-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
