crypto: atmel-aes - change algorithm priorities
Increase the algorithm priorities so the hardware acceleration is now preferred to the software computation: the "aes-generice" driver uses 100 as priority. Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
