[PATCHi v2] dt-bindings: add device tree binding for Arm TrustZone CryptoCell crypto engine

[Gilad Ben-Yossef]

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.

Changes from v1:
- Change node name to reflect type of device in example as pointed out by
  Rob Herring.
