crypto: caam - add backward compatible string sec4.0
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". Signed-off-by: Shengzhou Liu <Shengzhou.Liu@freescale.com> 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.
