crypto: dts - Addition of missing SEC compatibile property in c29x device tree

The driver is compatible with SEC version 4.0, which was missing from
device tree resulting that the caam driver doesn't gets probed. Since
SEC is backward compatible with older versions, so this patch adds those
missing versions in c29x device tree.
