OK, I got a bit carried away, and converted a bunch of platforms in
drivers/crypto (build tested only, except for the virtio driver)

crypto: qce - switch to skcipher API

crypto: nitrox - remove cra_type reference to ablkcipher
crypto: bcm-spu - switch to skcipher API
crypto: atmel-tdes - switch to skcipher API
crypto: atmel-aes - switch to skcipher API
crypto: s5p - switch to skcipher API

I pushed the branch to kernelci, so hopefully we'll get some automated
results, but I think only a small subset of these are boot tested atm.
