Subject: [PATCH] dt-bindings: add device tree binding for Arm TrustZone CryptoCell crypto engine

The Arm TrustZone CryptoCell is a hardware security engine. This patch
adds DT bindings for its Rich Execution Environment crypto engine.

A driver supporting this device is already present in the staging tree.
