crypto: omap-aes - fix crypto engine initialization order
The crypto engine must be initialized before registering algorithms, otherwise the test manager will crash as it attempts to execute tests for the algos while they are being registered. Fixes: 0529900a01cb ("crypto: omap-aes - Support crypto engine framework") Signed-off-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
