The Security System is a hardware cryptographic accelerator that support
AES/MD5/SHA1/DES/3DES/PRNG algorithms.
It could be found on many Allwinner SoC.

This patch enable the Security System on the Allwinner A20 SoC Device-tree.

This looks wrong. It's either sun4i-a10 or sun7i-a20.

It looks good otherwise.

Thanks!
