PATCH 1/1 ARM: dts: imx: Remove optional 'fsl,sec-era' property

From: Fabio Estevam <[email protected]>

Since commit 654f2b937b38 ("crypto: caam - allow retrieving 'era' from register") the CAAM driver is capable of obtaining the era version by reading the appropriate CAAM registers, so let the CAAM driver discover the era version in run-time instead of hardcoding such information in the device tree.

According to Documentation/devicetree/bindings/crypto/fsl-sec4.txt the 'fsl,sec-era' is an optional property and this can be safely removed now.
