Hi,

This series of patches is a global rework of the mtk driver.
Fix bug - incomplete DMA data transfer when SG buffer dst.len != src.len

It also updates some part of the code to make them more generic. For
instance the crypto request queue management supports both async block
cipher and AEAD requests, which allows us to add support the the GCM mode.
GMAC mode is not supported yet.

Current implementation was validated using the tcrypt
module running modes:
- 10: ecb(aes), cbc(aes), ctr(aes), rfc3686(ctr(aes))
- 35: gcm(aes)
- 2,6,11,12: sha1, sha2 family

tcrypt speed test was run with modes:
- 211: rfc4106(gcm(aes)), gcm(aes)
- 500: ecb(aes), cbc(aes), ctr(aes), rfc3686(ctr(aes))
- 403 ~ 406: sha1, sha2 family

IxChariot multiple pairs throughput 24 hours test:
- IPSec VPN
- MACSec
