apm821xx: backport and reassign crypto4xx patches
This patch backports several patches that went upstream into
Herbert Xu's cryptodev-2.6 tree:
crypto: Use zeroing memory allocator instead of allocator/memset
crypto: crypto4xx - performance optimizations
crypto: crypto4xx - convert to skcipher
crypto: crypto4xx - avoid VLA use
crypto: crypto4xx - add aes-ctr support
crypto: crypto4xx - properly set IV after de- and encrypt
crypto: crypto4xx - extend aead fallback checks
crypto: crypto4xx - put temporary dst sg into request ctx
The older, outstanding patches from 120-wxyz series have been
upstreamed as well and therefore they have been reassigned to
fit into the series.
