crypto: caam/qi - add ablkcipher and authenc algorithms
Add support to submit ablkcipher and authenc algorithms
via the QI backend:
-ablkcipher:
cbc({aes,des,des3_ede})
ctr(aes), rfc3686(ctr(aes))
xts(aes)
-authenc:
authenc(hmac(md5),cbc({aes,des,des3_ede}))
authenc(hmac(sha*),cbc({aes,des,des3_ede}))
caam/qi being a new driver, let's wait some time to settle down without
interfering with existing caam/jr driver.
Accordingly, for now all caam/qi algorithms (caamalg_qi module) are
marked to be of lower priority than caam/jr ones (caamalg module).
