* Hisilicon hip07 Security Accelerator (SEC)

Required properties:
- compatible: Must contain one of
  - "hisilicon,hip06-sec"
  - "hisilicon,hip07-sec"
- reg: Memory addresses and lengths of the memory regions through which
  this device is controlled.
  Region 0 has registers to control the backend processing engines.
  Region 1 has registers for functionality common to all queues.
  Regions 2-18 have registers for the 16 individual queues which are isolated
  both in hardware and within the driver.
- interrupts: Interrupt specifiers.
  Refer to interrupt-controller/interrupts.txt for generic interrupt client node
  bindings.
  Interrupt 0 is for the SEC unit error queue.
  Interrupt 2N + 1 is the completion interrupt for queue N.
  Interrupt 2N + 2 is the error interrupt for queue N.
- dma-coherent:  The driver assumes coherent dma is possible.

Optional properties:
- iommus: The SEC units are behind smmu-v3 iommus.
  Refer to iommu/arm,smmu-v3.txt for more information.
