From: Shengzhou Liu <Shengzhou.Liu@xxxxxxxxxxxxx>
In some device trees of previous version, there were string "fsl,sec4.0".
To be backward compatible with device trees, we first check "fsl,sec-v4.0",
if it fails, then check for "fsl,sec4.0".

extended to include new hash and rng code, which was omitted from
the previous version of this patch during a rebase of the SDK
version.
