[PATCH 2/2] kernel: crypto: add cavium cptpf module

[Daniel Danzberger]

Provides hardware crypto support for some cavium platforms like the
octeontx. Cryptodev support is also enabled for use from userspace.

Requires 2 firmwares (cpt8x-mc-ae.out + cpt8x-mc-se.out).
Provided by those packages:
 cavium-firmware-cpt-ae
 cavium-firmware-cpt-se

Supported ciphers:
-
root at OpenWrt:/# cat /proc/crypto | grep driver
driver       : cavium-ecb-des3_ede
driver       : cavium-cbc-des3_ede
driver       : cavium-cfb-aes
driver       : cavium-ecb-aes
driver       : cavium-cbc-aes
driver       : cavium-xts-aes
-
