-Required properties:
-- compatible: Should be one of -
- "arm,cryptocell-713-ree"
- "arm,cryptocell-703-ree"
- "arm,cryptocell-712-ree"
- "arm,cryptocell-710-ree"
- "arm,cryptocell-630p-ree"
-- reg: Base physical address of the engine and length of memory mapped region.
-- interrupts: Interrupt number for the device.
-
-Optional properties:
-- clocks: Reference to the crypto engine clock.
-- dma-coherent: Present if dma operations are coherent.
