crypto: caam - refactor encryption descriptors generation
Refactor the generation of the authenc, ablkcipher shared descriptors and exports the functionality, such that they could be shared with the upcoming caam/qi (Queue Interface) driver. Signed-off-by: Horia Geantă <horia.geanta@nxp.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
